Air injection systems include certain safety checks which prevent exhaust from forcing its way back toward the pump, or from overloading the manifold. Standard Motor A.I.R. diverter valves are one such component. These replacements are manufactured from durable materials, built to factory specs, and will easily install in the stock location. If your bypass, diverter, or check valve is damaged or missing, find the Standard Motor part to fit your specific make and model.
