Greddy Blow Off Valves are easily adjustable to prevent both premature boost leakage and compressor surge. Each is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer. The spring stiffness adjustment screw and 3 different sizes give the Greddy use the option to match vehicles with mild upgrades to heavily tuned engines. Also available in an easy to install kit form for many turbocharged vehicles. The new Greddy Type-RS Blow Off Valve allows for greater performance in a compact size. Improved response and increased pressure are achieved through carefully selected spring rates and a large 40mm valve. It features CNC machined 8 discharge ports that draw in the surrounding air to amplify the blow-off sound. The Type-RS is compatible with the standard GReddy Blow-off Valve flanges.
