Our Pressure Relief Piston valve is a bolt-on valve that replaces the factory plastic Diverter Valve which often, fails.
The Valve works perfectly without any check engine light in the dashboard, solenoid driven operation guaranties ECU communication. The Piston type valve is engineered to remedy the issues experienced with the factory valves when their diaphragm rapture or when their piston breaks, resulting in boost leaks and premature wear of the turbocharger.
Our valve is designed to work for a lifetime without fail, because it is serviceable.
