GReddy Blow Off Valve is easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each valve 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 the three different sizes give the GReddy user the option to match vehicles with mild upgrades to heavily tuned engines.
The GReddy Type RZ Blow off Valve state-of-the art design 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. The real unique feature of the Type-RS blow off valve is the CNC machined 8 discharge ports that draw in the surrounding air to amplify the blow-off sound. The Type-RZ is compatible with the standard GReddy Blow-off Valve flanges.
Availability: Usually ships in 3-5 business days.
