Product Description
The Dorman Secondary Air Injection Check Valve 911-622 is a replacement part for vehicles equipped with a secondary air injection system. This valve prevents exhaust gases from flowing back into the air pump, protecting the pump from damage and ensuring proper operation of the emissions system. Secondary air injection systems help reduce cold-start emissions by injecting fresh air into the exhaust manifold.
