Our decompression piston valve kit is a complete bolt-on kit. The valve works perfectly without triggering a check engine light in the dash. The Piston-type valve is designed to remedy the problems experienced with factory valves when their diaphragm ruptures or when their piston breaks, leading to boost leaks and premature turbocharger wear.
Our valve is designed to operate for a lifetime without fail because it is repairable.
