This downstream O2 sensor monitors the exhaust gas after the catalytic converter, providing precise feedback on the air-fuel ratio (Lambda) to the ECU. By keeping the mixture balanced, you’ll enjoy improved fuel efficiency, lower emissions, and better catalytic converter protection from rich or lean conditions.\u003c\/p\u003e \u003cp\u003eCompatible across key 2.5L Subaru platforms, it fits Forester 2008–2013 4Cyl 2.5L DOHC models and Impreza variants from 2008–2014, including EMPI TURBO 25GT\/25GT-S, WRX, WRX-S, and STI configurations. The part uses OEM reference 22690-AA900 with multiple cross references, ensuring a reliable interchange and a precise drop-in replacement.\u003c\/p\u003e \u003cp\u003eOriginating from Mainland China, each unit is thoroughly tested to meet IWOKPHD’s quality standards.
