Greddy Type R Universal Blow-Off Valve
Turbo lag is the enemy of any turbocharged vehicle. Greddy's Blow Off Valves are easily adjustable to prevent both premature boost leakage and compressor surge. Each is made of durable cast billet aluminum frame, and the valve to diaphragm ratio provides performance that cheap piston types can not offer. The spring stiffness adjustment screw and the two different sizes give the Greddy user the ability to match any vehicle setup from stock to heavily tuned.
