Pressure Relief Piston Valve

Our Pressure Relief Piston Valve is a bolt-on replacement for the factory plastic Diverter Valve, which often fails. This valve operates without triggering a check engine light, thanks to its solenoid-driven operation that ensures proper ECU communication. Engineered to address issues like diaphragm rupture or piston breakage in factory valves, it prevents boost leaks and premature turbocharger wear.

Designed for lifetime performance, our valve is fully serviceable.
