Our Pressure Relief Piston Valve kit, is a complete bolt-on kit. The Valve works perfectly without triggering any check engine light in the dashboard. The Piston type valve is engineered to remedy the issues experienced with the factory valves when their diaphragm raptures or when their piston breaks, which results in boost leaks and premature wear of the turbocharger.

Our valve is designed to work a lifetime without fail because it is serviceable.
