When aftermarket sound systems, high-draw lighting, or performance electronics are installed, the stock unit suffers from thermal saturation and excessive voltage drop at idle speeds. Sustained current demand overtaxes OEM diodes and stator coils, resulting in system voltage sagging below 13.0V, premature battery degradation, dimming headlights, and erratic electronic control module (ECM) operation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-demand duty cycles, this 250-amp alternator utilizes heavy-gauge copper stator windings, a precision dynamic-balanced rotor, and high-temp sealed bearings to minimize parasitic drag and dissipate heat effectively. Featuring an internal solid-state voltage regulator, it stabilizes system charging between 13.5V and 14.5V across the entire RPM band. The housing retains factory mounting ears, pulley geometry, and plug polarity, facilitating direct bolt-in installation onto the \u003cstrong\u003eFB25\u003c\/strong\u003e engine block with zero wiring harness splicing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 250 Amp High Output Alternator (Part # 44010)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2015-2017 Subaru Legacy 2.5L\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eFB25 \/ BN\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e175 hp \/ 174 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eA002TX3382, A002TX3382AC, A002TX3382ZC, A2TX3382, A2TX3382AC, A2TX3382ZC, 23700-AA91, 23700-AA91A, 23700-AA91B\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015 Subaru Legacy 2.5L (Base, Premium, Limited)\u003c\/li\u003e\n  \u003cli\u003e2016 Subaru Legacy 2.5L (Base, Premium, Sport, Limited)\u003c\/li\u003e\n  \u003cli\u003e2017 Subaru Legacy 2.5L (Base, Premium, Sport, Limited)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the BN Legacy?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2017 Subaru Legacy equipped with the \u003cstrong\u003eFB25\u003c\/strong\u003e 2.5L engine. \u003cstrong\u003eDoes not fit 3.6L H6 models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to upgrade my vehicle wiring when installing this unit?\u003c\/h4\u003e\n\u003cp\u003eWhile this alternator utilizes the factory connector and charge post, upgrading the main battery charge wire and chassis ground straps (Big 3 upgrade) is strongly recommended to handle 250-amp flow without thermal resistance.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Performance Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain consistent electrical stability and uninterrupted sensor signals on your boxer powertrain, ensuring mission-critical electronics run efficiently even under heavy demand.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67901131882744,"sku":"DS-E3X9VFILO","price":438.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-output-alternator-for-subaru-legacy-2015-2017-2-5l-1.jpg?v=1793334090","url":"https:\/\/performancechiptuning.com\/products\/high-output-alternator-for-subaru-legacy-2015-2017-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
