斯巴鲁翼豹2008 2.5T后氧传感器22690-AA900替换磨损件恢复动力

When your Subaru Impreza 2008 2.5T shows check engine light, higher fuel consumption, weak acceleration, or rough idle, it typically indicates the rear oxygen sensor aging or failure. This sensor provides real-time feedback of the air-fuel ratio to help the ECU adjust fuel injection for power and economy. This product is a replacement for the original OEM number 22690-AA900 and fits 2008 Subaru Impreza 2.5T. Ensure sensor threads are clean and tighten to the specified torque; avoid cable entanglement or contact with high-temperature exhaust areas.
