斯巴鲁森林人氧传感器22690-AB010，直接替换原厂件，提升动力，减少尾气排放。

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.
