Secondary Air Injection Check Valve with Gasket for Chevrolet Colorado GMC Hummer

Product Details

• [Important Role]: The secondary air injection check valve plays an important role in reducing vehicle emissions. It promotes combustion of unburned fuel by injecting air into the exhaust pipe when the engine is started, thus reducing harmful emissions, especially during cold starts. A failed check valve can cause check engine light to illuminate and exhaust emissions to increase. If you notice any of these symptoms above, you need to replace your air check valve.
