Using the OEM-referenced part number 22690-AA990, this sensor helps your engine maintain an optimal air-to-fuel ratio, improves fuel efficiency, reduces emissions, and supports smoother idle under varying driving conditions.\u003c\/p\u003e \u003ch2\u003eMain Description\u003c\/h2\u003e\n\u003cp\u003eThis downstream oxygen sensor uses magnetic induction technology and a heating element to deliver faster warm-up and stable readings. By accurately measuring the exhaust gas composition downstream, it provides critical feedback to the engine control unit (ECU) so your vehicle can adjust fuel delivery in real time. Replacing a faulty downstream sensor can restore precise fuel trimming, reduce catalytic converter strain, and help preserve performance across city and highway driving alike.\u003c\/p\u003e \u003ch3\u003eCompatibility \u0026amp; Application\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.0XT Premium Wagon 4-Door — 2.0L 1998CC Turbocharged H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.0XT Touring Wagon 4-Door — 2.0L 1998CC Turbocharged H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.5i Limited Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.5i Premium Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.5i Touring Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester 2.5i Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester X Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester XS Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester XSL Wagon 4-Door — 2.5L 2498CC Naturally Aspirated H4\u003c\/li\u003e \u003cli\u003eFor 2014-2015 Subaru Forester XT Wagon 4-Door — 2.0L 1998CC Turbocharged H4\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eNote: Compatibility is based on part number 22690-AA990 (also listed as 22690AA990 or 22690 AA990).
