Subaru Forester Oxygen Sensor 22690-AB010, direct replacement for OEM part, improves power, reduces exhaust emissions.

When your Subaru Forester exhibits idle instability, sluggish acceleration, increased fuel consumption, or check engine light, this usually indicates the oxygen sensor aging or failure. It normally forwards real-time air-fuel ratio signals to the ECU to optimize combustion, improving power and reducing emissions. This is a direct OEM replacement with OEM number 22690-AB010, fits many Subaru Forester models (e.g., 2009-2013 2.5L/2.0L). Install only when the engine is cold; clean threads before removing old sensor; use a dedicated socket and apply anti-seize; torque to spec to prevent thread damage.
