Description

The 2008 Ford Fusion Air Injection Pump is a critical component of the vehicle's emission control system. This pump, also known as the Secondary Air Injection (AIR) pump, supplies metered air into the exhaust system during engine warm-up to reduce emissions. It operates by drawing dry, filtered air from downstream of the MAF/IAT sensor and is controlled by the vehicle's PCM for a brief period after startup. Proper function of this pump helps the Fusion meet emission standards and maintain engine efficiency. When replacing this part, it is important to verify compatibility with your specific 2008 Fusion model, as OEM part numbers may vary.
