Organization, Consolidation and Presentation of Financial Statements [Abstract]
INTRODUCTION AND TRANSITION TO STANDALONE COMPANY	INTRODUCTION The accompanying Condensed Consolidated Financial Statements and notes present the condensed consolidated statements of operations, balance sheets, and cash flows of PHINIA Inc. (“PHINIA” or the “Company”). PHINIA is a leader in the development, design and manufacture of integrated components and systems that optimize performance, increase efficiency and reduce emissions in combustion and hybrid propulsion for commercial vehicles and industrial applications (medium-duty and heavy-duty trucks, buses and other off-highway construction, marine, agricultural and industrial applications) and light vehicles (passenger cars, trucks, vans and sport-utility vehicles). The Company is a global supplier to most major original equipment manufacturers (“OEMs”) seeking to meet and exceed increasingly stringent global regulatory requirements and satisfy consumer demands for an enhanced user experience. Additionally, the Company offers a wide range of original equipment service (“OES”) solutions and remanufactured products as well as an expanded range of products for the independent (non-OEM) aftermarket. Transition to Standalone Company On December 6, 2022, BorgWarner Inc. (“BorgWarner,” or “Former Parent”) announced plans for the complete legal and structural separation of BorgWarner’s Fuel Systems and Aftermarket businesses from BorgWarner by the spin-off of its wholly-owned subsidiary, PHINIA, which was formed on February 9, 2023 (the “Spin-Off”).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Prior to the Spin-Off on July 3, 2023, the historical financial statements of PHINIA were prepared on a stand-alone combined basis and were derived from BorgWarner’s consolidated financial statements and accounting records as if the Fuel Systems and Aftermarket businesses of BorgWarner had been part of PHINIA for all periods presented. Accordingly, for periods prior to July 3, 2023, our financial statements are presented on a combined basis and for the periods subsequent to July 3, 2023 are presented on a consolidated basis (all periods hereinafter are referred to as “consolidated financial statements”). The Company's Condensed Consolidated Financial Statements were prepared in accordance with accounting principles in the United States of America ("U.S. GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Certain information and footnote disclosures normally included in annual financial statements were condensed or omitted as permitted by such rules and regulations. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The balance sheet as of December 31, 2022 was derived from the audited financial statements as of that date. Certain amounts for the prior periods presented were reclassified to conform to the current period presentation. Amounts that were previously presented as Due from BorgWarner, current and Due from BorgWarner, non-current are now presented within Receivables, net and Investments and long-term receivables, respectively. Amounts that were previously presented as Due to BorgWarner, current are now presented within Accounts payable and Other current liabilities. Amounts that were previously presented in Due to BorgWarner, non-current are now presented in Other non-current liabilities. Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. The Condensed Consolidated Financial Statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the periods presented prior to the Spin-Off. The Condensed Consolidated Statements of Operations include all revenues and costs directly attributable to the Company, including costs for facilities, functions, and services utilized. Costs for certain centralized functions and programs provided and administered by BorgWarner were charged directly to the Company prior to Spin-Off. These centralized functions and programs included, but were not limited to research and development and information technology. A portion of BorgWarner’s total corporate expenses were allocated to the Company for services rendered by BorgWarner prior to the Spin-Off. These expenses included the cost of corporate functions and resources, including, but not limited to, executive management, finance, accounting, legal, human resources, research and development and sales. Additionally, a portion of the Company’s corporate expenses were allocated to BorgWarner for charges incurred related to subsidiaries of BorgWarner historically supported by the Company, primarily related to information technology. These expenses were allocated based on direct usage when identifiable or, when not directly identifiable, on the basis of proportional net revenues, legal entities, headcount or weighted-square footage, as applicable. The Company considers the basis on which the expenses have been allocated to reasonably reflect the utilization of services provided to, or the benefit received by, both the Company and BorgWarner during the periods presented. However, the allocations may not reflect the expenses the Company would have incurred if the Company had been a standalone company for the periods presented prior to July 3, 2023. The nine months ended September 30, 2023 included net corporate allocation expenses incurred prior to the Spin-Off totaling $89 million. For the three and nine months ended September 30, 2022 net corporate allocation expenses totaled $26 million and $95 million, respectively. Corporate allocation expenses were primarily included in Selling, general and administrative expenses.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERS The Company manufactures and sells products, primarily to OEMs of commercial vehicle industrial applications and light vehicles, to certain tier one vehicle systems suppliers and into the aftermarket. The Company’s payment terms are based on customary business practices and vary by customer type and products offered. The Company has evaluated the terms of its arrangements and determined that they do not contain significant financing components. Generally, revenue is recognized upon shipment or delivery; however, a limited number of the Company’s customer arrangements for its highly customized products with no alternative use provide the Company with the right to payment during the production process. As a result, for these limited arrangements, revenue is recognized as goods are produced and control transfers to the customer using the input cost-to-cost method. The Company recorded a contract asset of $2 million at both September 30, 2023 and December 31, 2022 for these arrangements. These amounts are reflected in Prepayments and other current assets in the Company’s Condensed Consolidated Balance Sheets. In limited instances, certain customers have provided payments in advance of receiving related products, typically at the onset of an arrangement prior to the beginning of production. These contract liabilities are reflected as Other current liabilities in the Condensed Consolidated Balance Sheets and were $3 million at both September 30, 2023 and December 31, 2022. These amounts are reflected as revenue over the term of the arrangement (typically 3 to 7 years) as the underlying products are shipped and represent the Company’s remaining performance obligations as of the end of the period. The following table represents a disaggregation of revenue from contracts with customers by reportable segment and region for the three and nine months ended September 30, 2023 and 2022. Refer to Note 21, “Reportable Segments And Related Information” to the Condensed Consolidated Financial Statements, for more information.

Research and Development [Abstract]
RESEARCH AND DEVELOPMENT COSTS	RESEARCH AND DEVELOPMENT COSTSThe Company’s net research & development (“R&D”) expenditures are primarily included in Selling, general and administrative expenses of the Condensed Consolidated Statements of Operations. Customer reimbursements are netted against gross R&D expenditures as they are considered a recovery of cost. Customer reimbursements for prototypes are recorded net of prototype costs based on customer contracts, typically either when the prototype is shipped or when it is accepted by the customer. Customer reimbursements for engineering services are recorded when performance obligations are satisfied in accordance with the contract. Financial risks and rewards transfer upon shipment, acceptance of a prototype component by the customer or upon completion of the performance obligation as stated in the respective customer agreement. The Company has various customer arrangements relating to R&D activities that it performs at its various R&D locations. The following table presents the Company’s gross and net expenditures on R&D activities: Three months ended September 30, Nine months ended September 30, (in millions) 2023 2022 2023 2022 Gross R&D expenditures $ 45 $ 49 $ 143 $ 151 Customer reimbursements (21) (25) (62) (73) Net R&D expenditures $ 24 $ 24 $ 81 $ 78

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING The Company’s restructuring expenditures are primarily included in Other operating expense (income), net of the Condensed Consolidated Statements of Operations. The Company’s restructuring activities are undertaken as necessary to execute management’s strategy and streamline operations, consolidate and take advantage of available capacity and resources, and ultimately achieve net cost reductions. Restructuring activities include efforts to integrate and rationalize the Company’s business and to relocate operations to best-cost locations. The Company’s restructuring expenses consist primarily of employee termination benefits (principally severance and/or other termination benefits) and other costs, which are primarily professional fees and costs related to equipment moves. Three months ended September 30, 2023 Nine months ended September 30, 2023 (in millions) Fuel Systems Aftermarket Total Fuel Systems Aftermarket Total Employee termination benefits $ 3 $ — $ 3 $ 7 $ 1 $ 8 Other 1 — 1 2 — 2 Total restructuring expense $ 4 $ — $ 4 $ 9 $ 1 $ 10 Three months ended September 30, 2022 Nine months ended September 30, 2022 (in millions) Fuel Systems Aftermarket Total Fuel Systems Aftermarket Total Employee termination benefits $ — $ — $ — $ 2 $ — $ 2 Other 3 — 3 6 — 6 Total restructuring expense $ 3 $ — $ 3 $ 8 $ — $ 8 The following table displays a roll forward of the restructuring liability recorded within the Company’s Condensed Consolidated Balance Sheets and the related cash flow activity: (in millions) Employee termination benefits Other Total Balance at January 1, 2023 $ 20 $ — $ 20 Restructuring expense, net 8 2 10 Cash payments (17) (2) (19) Balance at September 30, 2023 11 — 11 Less: Non-current restructuring liability (1) — (1) Current restructuring liability at September 30, 2023 $ 10 $ — $ 10 (in millions) Employee termination benefits Other Total Balance at January 1, 2022 $ 60 $ — $ 60 Restructuring expense, net 2 6 8 Cash payments (36) (5) (41) Foreign currency translation adjustment and other (4) — (4) Balance at September 30, 2022 22 1 23 Less: Non-current restructuring liability (5) — (5) Current restructuring liability at September 30, 2022 $ 17 $ 1 $ 18 During the three and nine months ended September 30, 2023, the Company recorded $4 million and $10 million, respectively, of restructuring costs for individually approved restructuring actions that primarily related to reductions in headcount in the Fuel Systems segment. In 2019, the Company announced a restructuring plan to reshape and realign its global technical center footprint and reduce salaried and contract staff. The Company recorded charges of $8 million during the nine months ended September 30, 2022, primarily related to employee severance and equipment moves in the Fuel Systems segment. The actions under this program are complete. Estimates of restructuring expense are based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts paid for such activities may differ from amounts initially recorded. Accordingly, the Company may record revisions of previous estimates by adjusting previously established accruals. The Company continues to evaluate different options across its operations to reduce existing structural costs. The Company will recognize restructuring expense associated with any future actions at the time they are approved and become probable or are incurred. Any future actions could result in significant restructuring expense.

INCOME TAXES

INCOME TAXES	9 Months Ended
	Sep. 30, 2023
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s provision for income taxes is based upon an estimated annual effective tax rate for the year applied to domestic and foreign income. On a quarterly basis, the annual effective tax rate is adjusted, as appropriate, based upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. The Company’s effective tax rate for the three months ended September 30, 2023 and 2022 was 74% and 26%, respectively. The effective tax rate for the three months ended September 30, 2023 increased as compared to the prior year as a result of a change in the jurisdictional mix of pre-tax earnings, most notably an increase in pre-tax losses where no tax benefit is recognized, as well as an increase in the estimated annual effective tax rate in the current quarter due to increases in the U.S. taxes on foreign earnings based on the post Spin-Off structure. The Company’s effective tax rate for the nine months ended September 30, 2023 and 2022 was 48% and 26%, respectively. The effective tax rate for the nine months ended September 30, 2023 increased as compared to the prior year as a result of a change in the jurisdictional mix of pre-tax earnings, most notably an increase in pre-tax losses where no tax benefit is recognized. The estimated annual effective tax rate increased in the current quarter due to increases in the U.S. taxes on foreign earnings based on the post Spin-Off structure. The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which vary from those in the U.S., jurisdictions with pretax losses for which no tax benefit could be realized, U.S. taxes on foreign earnings, and permanent differences between book and tax treatment for certain items including enhanced deduction of research and development expenses in certain jurisdictions. For periods ended on or prior to July 3, 2023, the Company’s operations have been included in BorgWarner’s U.S. federal consolidated tax return, certain foreign tax returns, and certain state tax returns. For the purposes of these financial statements, the Company’s income tax provision was computed as if the Company filed separate tax returns (i.e., as if the Company had not been included in the consolidated income tax return group with BorgWarner). The separate return method applies ASC 740 to the Condensed Consolidated Financial Statements of each member of a consolidated tax group as if the group member were a separate taxpayer. As a result, actual tax transactions included in the consolidated financial statements of BorgWarner may not be included in these Condensed Consolidated Financial Statements. Further, the Company’s tax results as presented in the Condensed Consolidated Financial Statements may not be reflective of the results that the Company expects to generate in the future. Also, the tax treatment of certain items reflected in the Condensed Consolidated Financial Statements may not be reflected in the Consolidated Financial Statements and tax returns of BorgWarner.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLESDuring the fourth quarter of each year, the Company assesses its goodwill assigned to each of its reporting units for impairment by either performing a qualitative assessment or a quantitative analysis. In addition, the Company may test goodwill in between annual test dates if an event occurs or circumstances change that could more-likely-than-not reduce the fair value of a reporting unit below its carrying value. Similar to goodwill, the Company performs an annual impairment test for indefinite-lived intangibles other than goodwill (trade names) using a qualitative analysis during the fourth quarter each year to determine if it is more-likely-than-not that the fair value of the intangible asset is less than its respective carrying value. If the Company elects to perform or is required to perform a quantitative analysis, the test consists of a comparison of the fair value of the indefinite-lived intangible asset to the carrying value of the asset as of the impairment testing date. No events or circumstances were noted in the first nine months of 2023 requiring additional assessment or testing. Future changes in the judgments, assumptions and estimates from those used in acquisition-related valuations and goodwill impairment testing, including discount rates or future operating results and related cash flow projections, could result in significantly different estimates of the fair values in the future. An increase in discount rates, a reduction in projected cash flows or a combination of the two could lead to a reduction in the estimated fair values, which may result in impairment charges that could materially affect the Company’s financial statements in any given year. A summary of the components in the carrying amount of goodwill as of September 30, 2023 and December 31, 2022 is as follows: (in millions) Fuel Systems Aftermarket Total Gross goodwill balance, December 31, 2022 $ 58 $ 545 $ 603 Accumulated impairment losses — (113) (113) Net goodwill balance, December 31, 2022 $ 58 $ 432 $ 490 Goodwill during the period: Translation adjustment — (4) (4) Net goodwill balance, September 30, 2023 $ 58 $ 428 $ 486 The Company’s other intangible assets consist of the following: September 30, 2023 December 31, 2022 (in millions) Estimated useful lives (years) Gross carrying amount Accumulated amortization Net carrying amount Gross carrying amount Accumulated amortization Net carrying amount Amortized intangible assets: Patented and unpatented technology 14 - 15 $ 144 $ 39 $ 105 $ 144 $ 30 $ 114 Customer relationships 14 - 15 263 97 166 263 85 178 Total amortized intangible assets 407 136 271 407 115 292 Unamortized trade names 140 — 140 140 — 140 Total other intangible assets $ 547 $ 136 $ 411 $ 547 $ 115 $ 432

As of December 31, 2022, the estimated fair value of the Company’s senior unsecured notes totaled $23 million, which was $3 million higher than carrying value for the same period. Fair market values of the long-term debt are developed using observable values for similar debt instruments, which are considered Level 2 inputs as defined by ASC Topic 820. The carrying values of the Company’s other debt facilities approximate fair value. The fair value estimates do not necessarily reflect the values the Company could realize in the current markets. Credit Agreement On July 3, 2023, the Company entered into a $1.225 billion Credit Agreement consisting of a $500 million revolving credit facility (the “Revolving Facility”), a $300 million Term Loan A Facility (the “Term Loan A Facility”) and a $425 million Term Loan B Facility (the “Term Loan B Facility”; together with the Revolving Facility and the Term Loan A Facility, collectively, the “Facilities”) in correlation with the Spin-Off that occurred on the same date. Subject to extension by the lenders, at their option, upon the Company’s request, the Facilities mature on July 3, 2028; provided, however, that if earlier, the Revolving Facility and the Term Loan A Facility will mature 91 calendar days prior to the scheduled maturity of the Term Loan B Facility or any refinancing or replacement thereof in an aggregate principal amount exceeding $100 million that is secured pari passu with the Revolving Facility and the Term Loan A Facility and matures on or prior to July 3, 2028. Borrowings under the Credit Agreement bear interest at varying rates, depending on the type of loan and, in some cases, the rates of designated benchmarks and the Company’s related election. For borrowings under the Credit Agreement, the Company may choose among the following interest rates: (i) solely in the case of U.S. dollar-denominated loans, an interest rate equal to the highest of (1) the prime rate in effect from time to time, (2) the federal funds effective rate in effect from time to time plus 0.5%, (3) adjusted term Secured Overnight Financing Rate (“SOFR”) (which includes a 0.10% credit spread adjustment to term SOFR) for a one month interest period plus 1.00%, and (4) 1.00%, in each case plus a rate (x) with respect to the Revolving Facility and the Term Loan A Facility, ranging from 1.50% to 2.00% depending on the Company’s consolidated net leverage ratio or (y) with respect to the Term Loan B Facility, 3.00%; or (ii) an interest rate equal to (1) solely in the case of U.S. dollar-denominated loans, adjusted term SOFR, (2) solely in the case of euro-denominated loans, Euro Interbank Offered Rate (“EURIBOR”), or (3) solely in the case of pound sterling-denominated loans, adjusted Sterling Overnight Index Average Reference Rate (“SONIA”) (which includes a 0.0326% credit spread adjustment to SONIA), as applicable, in each case for the applicable interest period plus a rate (x) with respect to adjusted term SOFR for the Revolving Facility and the Term Loan A Facility, EURIBOR and SONIA, ranging from 2.50% to 3.00% depending on our consolidated net leverage ratio, and (y) with respect to adjusted term SOFR for the Term Loan B Facility, 4.00%. Additionally, the Company will pay a quarterly commitment fee based on the actual daily amount of the available Revolving Facility commitment. Proceeds of the Term Loan A Facility and the Term Loan B Facility were used only for certain payments in connection with the Spin-Off and the Credit Agreement. Proceeds of the Revolving Facility were used for certain payments in connection with the Spin-Off and the Credit Agreement and for working capital and general corporate purposes. As of September 30, 2023, the Company had $75 million of outstanding borrowings under the Revolving Facility. The Credit Agreement contains customary covenants relating to us and our subsidiaries concerning, among other things, investments, dispositions of assets, indebtedness, liens on assets, and dividends and other distributions. Solely in respect of the Revolving Facility and the Term Loan A Facility, the Credit Agreement also contains financial covenants requiring (i) the consolidated net leverage ratio of the Company, determined as of the end of each fiscal quarter, not to exceed 3.00 to 1.00 (or, at our election and subject to certain conditions, 3.50 to 1.00 for the period in which such election is made and the next succeeding testing period and, thereafter, 3.25 to 1.00 for the next two succeeding testing periods) and (ii) the consolidated interest coverage ratio of the Company, determined as of the end of each fiscal quarter, to be at least 3.00 to 1.00. The Company was in compliance with all covenants as of September 30, 2023.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS ASC Topic 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows: Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC Topic 820: A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business. B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost). C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models). The following tables classify assets and liabilities measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022: Basis of fair value measurements (in millions) Balance at September 30, 2023 Quoted prices in active markets for identical items Significant other observable inputs Significant unobservable inputs Valuation Assets: Foreign currency contracts $ 1 $ — $ 1 $ — A Liabilities: Foreign currency contracts $ (1) $ — $ (1) $ — A Basis of fair value measurements (in millions) Balance at December 31, 2022 Quoted prices in active markets for identical items Significant other observable inputs Significant unobservable inputs Valuation Assets: Foreign currency contracts $ 7 $ — $ 7 $ — A Liabilities: Foreign currency contracts $ (1) $ — $ (1) $ — A

Derivative Instruments and Hedging Activities Disclosure [Abstract]
FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS The Company’s financial instruments include cash and cash equivalents, marketable securities and accounts receivable. Due to the short-term nature of these instruments, their book value approximates their fair value. The Company’s financial instruments may also include long-term debt, interest rate and cross-currency swaps, commodity derivative contracts and foreign currency derivative contracts. All derivative contracts are placed with counterparties that have an S&P, or equivalent, investment grade credit rating at the time of the contracts’ placement. An adjustment for non-performance risk is considered in the estimate of fair value in derivative assets based on the counterparty credit default swap (“CDS”) rate. When the Company is in a net derivative liability position, the non-performance risk adjustment is based on its CDS rate. At September 30, 2023 and December 31, 2022, the Company had no derivative contracts that contained credit-risk-related contingent features. The Company uses foreign currency forward and option contracts to protect against exchange rate movements for forecasted cash flows, including capital expenditures, purchases, operating expenses or sales transactions designated in currencies other than the functional currency of the operating unit. In addition, the Company uses foreign currency forward contracts to hedge exposure associated with its net investment in certain foreign operations (net investment hedges). Foreign currency derivative contracts require the Company, at a future date, to either buy or sell foreign currency in exchange for the operating units’ local currency. As of September 30, 2023 and December 31, 2022, the United States dollar equivalent notional values of outstanding currency derivative instruments was $38 million and $309 million, respectively. These amounts were primary related to Euro and British Pound denominated hedging transactions. As of September 30, 2023 and December 31, 2022, the following amounts were recorded in the Condensed Consolidated Balance Sheets as being payable to or receivable from counterparties under ASC Topic 815: (in millions) Assets Liabilities Derivatives designated as hedging instruments Under Topic 815: Balance Sheet Location September 30, 2023 December 31, 2022 Balance Sheet Location September 30, 2023 December 31, 2022 Foreign currency Prepayments and other current assets $ 1 $ 7 Other current liabilities $ 1 $ 1 Effectiveness for cash flow hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into accumulated other comprehensive income (loss) (“AOCI”) and reclassified into income as the underlying operating transactions are recognized. These realized gains or losses offset the hedged transaction and are recorded on the same line in the statement of operations. The initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method are recognized in AOCI. Effectiveness for net investment hedges is assessed at the inception of the hedging relationship and quarterly, thereafter. Gains and losses arising from these contracts that are included in the assessment of effectiveness are deferred into foreign currency translation adjustments and only released when the subsidiary being hedged is sold or substantially liquidated. The initial value of any component excluded from the assessment of effectiveness is recognized in income using a systematic and rational method over the life of the hedging instrument. Any difference between the change in fair value of the excluded component and amounts recognized in income under that systematic and rational method is recognized in AOCI. The table below shows deferred gains (losses) reported in AOCI as well as the amount expected to be reclassified to income in one year or less for designated net investment hedges. The amount expected to be reclassified to income in one year or less assumes no change in the current relationship of the hedged item at September 30, 2023 market rates.

Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS Pursuant to the Spin-Off, BorgWarner ceased to be a related party to PHINIA and accordingly, no related party transactions or balances have been reported subsequent to July 3, 2023. In connection with the Spin-Off, we entered into a number of agreements with BorgWarner to govern the Spin-Off and provide a framework for the relationship between the parties going forward, including a Transition Services Agreement, Tax Matters Agreement, and certain Contract Manufacturing Agreements. The following discussion summarizes activity between the Company and BorgWarner that occurred prior to the completion of the Spin-Off. Allocation of General Corporate and Other Expenses The Condensed Consolidated Statements of Operations include expenses for certain centralized functions and other programs provided and administered by BorgWarner that were charged directly to the Company prior to the Spin-Off. In addition, for purposes of preparing the financial statements on a carve-out basis, a portion of BorgWarner’s total corporate expenses was allocated to the Company. Similarly, certain centralized expenses incurred by the Company prior to the Spin-Off on behalf of subsidiaries of BorgWarner had been allocated to BorgWarner. See Note 1, “Basis Of Presentation,” for a discussion of the methodology used to allocate corporate expenses for purposes of preparing these financial statements on a carve-out basis for periods prior to July 3, 2023. Net corporate allocation expenses in nine months ended September 30, 2023 totaled $89 million, all of which were incurred prior to the Spin-Off. For the three and nine months ended September 30, 2022 net corporate allocation expenses totaled $26 million and $95 million, respectively. These expenses were primarily included in Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations. Related-Party Royalty Income and Related-Party R&D The Company participated in royalty arrangements and provided applications testing and other R&D services to BorgWarner prior to the Spin-Off. See Note 4, “Other operating expense (income), net” for additional information. Due from BorgWarner In the Condensed Consolidated Balance Sheets, the Company presents $142 million within Accounts receivable and $208 million within Investments and long-term receivables as of December 31, 2022.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company presents both basic and diluted earnings per share of common stock (“EPS”) amounts. Basic EPS is calculated by dividing net earnings by the weighted average shares of common stock outstanding during the reporting period. Diluted EPS is calculated by dividing net earnings by the weighted average shares of common stock and common stock equivalents outstanding during the reporting period. For periods prior to July 3, 2023, the denominator for basic and diluted earnings per share was calculated using the 47.0 million PHINIA ordinary shares outstanding immediately following the Spin-Off. The same number of shares was used to calculate basic and diluted earnings per share in those periods since no PHINIA equity awards were outstanding prior to the Spin-Off. The dilutive impact of stock-based compensation is calculated using the treasury stock method. The treasury stock method assumes that the Company uses the assumed proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future and compensation cost for future service that the Company has not yet recognized. The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share of common stock: Three months ended September 30, Nine months ended September 30, ( in millions, except per share amounts ) 2023 2022 2023 2022 Basic earnings per share: Net earnings $ 11 $ 89 $ 81 $ 187 Weighted average shares of common stock outstanding 47.0 47.0 47.0 47.0 Basic earnings per share of common stock $ 0.24 $ 1.89 $ 1.72 $ 3.98 Diluted earnings per share: Net earnings $ 11 $ 89 $ 81 $ 187 Weighted average shares of common stock outstanding 47.0 47.0 47.0 47.0 Effect of stock-based compensation 0.1 — — — Weighted average shares of common stock outstanding including dilutive shares 47.1 47.0 47.0 47.0 Diluted earnings per share of common stock $ 0.24 $ 1.89 $ 1.72 $ 3.98

Segment Reporting [Abstract]
REPORTING SEGMENTS AND RELATED INFORMATION	REPORTABLE SEGMENTS AND RELATED INFORMATION The Company’s business is comprised of two reportable segments, which are further described below. These segments are strategic business groups, which are managed separately as each represents a specific grouping of related automotive components and systems. • Fuel Systems. This segment provides advanced fuel injection systems, fuel delivery modules, canisters, sensors, electronic control modules and associated software. Our highly engineered fuel injection systems portfolio includes pumps, injectors, fuel rail assemblies, engine control modules, and complete systems, including software and calibration services, that reduce emissions and improve fuel economy for traditional and hybrid applications. • Aftermarket. Through this segment, the Company sells products to independent aftermarket customers and OES customers. Its product portfolio includes a wide range of products as well as maintenance, test equipment and vehicle diagnostics solutions. The Aftermarket segment also includes sales of starters and alternators to OEMs. Segment Adjusted Operating Income (“AOI”) is the measure of segment income or loss used by the Company. Segment AOI is comprised of segment operating income adjusted for restructuring, merger, acquisition and divestiture expense, intangible asset amortization expense, impairment charges, other net expenses and other items not reflective of ongoing operating income or loss.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	Prior to the Spin-Off on July 3, 2023, the historical financial statements of PHINIA were prepared on a stand-alone combined basis and were derived from BorgWarner’s consolidated financial statements and accounting records as if the Fuel Systems and Aftermarket businesses of BorgWarner had been part of PHINIA for all periods presented. Accordingly, for periods prior to July 3, 2023, our financial statements are presented on a combined basis and for the periods subsequent to July 3, 2023 are presented on a consolidated basis (all periods hereinafter are referred to as “consolidated financial statements”).
Basis of Presentation	The Company's Condensed Consolidated Financial Statements were prepared in accordance with accounting principles in the United States of America ("U.S. GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Certain information and footnote disclosures normally included in annual financial statements were condensed or omitted as permitted by such rules and regulations. In the opinion of management, all normal recurring adjustments necessary for a fair statement of results have been included. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The balance sheet as of December 31, 2022 was derived from the audited financial statements as of that date.Certain amounts for the prior periods presented were reclassified to conform to the current period presentation. Amounts that were previously presented as Due from BorgWarner, current and Due from BorgWarner, non-current are now presented within Receivables, net and Investments and long-term receivables, respectively. Amounts that were previously presented as Due to BorgWarner, current are now presented within Accounts payable and Other current liabilities. Amounts that were previously presented in Due to BorgWarner, non-current are now presented in Other non-current liabilities.
Use of Estimates	Management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and accompanying notes, as well as amounts of revenues and expenses reported during the periods covered by those financial statements and accompanying notes. The Condensed Consolidated Financial Statements may not be indicative of the Company’s future performance and do not necessarily reflect what the financial position, results of operations, and cash flows would have been had it operated as a standalone company during the periods presented prior to the Spin-Off.
Fair Value Measurement	ASC Topic 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC Topic 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair values as follows: Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques noted in ASC Topic 820: A. Market approach: Prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities or a group of assets or liabilities, such as a business. B. Cost approach: Amount that would be required to replace the service capacity of an asset (replacement cost). C. Income approach: Techniques to convert future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing and excess earnings models).
