Subaru Impreza Forester Oxygen Sensor – OEM 22641AA32A

Overview

A new oxygen sensor for Subaru Impreza and Forester models, referenced to OE numbers 22641AA32A, 22641AA490 and 22641AA211, and listed by the manufacturer for 2.5 AWD engines across the Impreza Estate (GG), Forester (SG_) and Forester (SH_) bodies. The sensor provides the air-fuel feedback the engine computer needs, so a worn unit produces a check engine light, higher fuel consumption, rough running and an emissions-test failure. With so many naturally aspirated 2.5 litre Subarus on New Zealand roads, this is a frequently needed part. The manufacturer states ISO 9001:2000 / ISO/TS 16949 quality certification and a 12-month warranty.
