STANDARD VALVE - DIVERTER

The Standard Ignition DV131 Secondary Air Injection Pump Check Valve is a direct-replacement component designed to maintain proper air flow within your vehicle's emission control system. This valve is engineered to fit the secondary air injection pump hose with a 1 1/4 inch diameter and plays a critical role in preventing exhaust gases from flowing back into the air injection system.

Constructed to meet OEM standards, this check valve helps reduce emissions, supports engine efficiency, and eliminates potential air injection pump failure caused by valve malfunction. It also prevents check valve leaks that can trigger engine warning lights, ensuring optimal engine performance.
