HKS Blow off Valve and Components

*NEW* Tial Sport Recirculating Bypass 50mm Diverter Bypass Valve

Brand new release from Tial, is their bypass / diverter 50mm valve. Perfect for those who want the large high flow Tial style BOV but want to diver the air back into the intake tracking.

Turbonetics Duo-35 Bypass / BOV Valve

This exclusive blow-off valve features a dual cross tunnel discharge system with various discharge designs. You can use one or two GT-K inspired horns to vent the pressurized air directly to atmosphere for that extra loud discharge. Without the horn, you can recirculate for tuning purposes and quieter operation.

Greddy Type RS Blow off Valve, 40mm Universal

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.

New Greddy RZ Blow Off Valve

GReddy Blow Off Valves are 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. There are many factors in matching a blow-off valve to an application, valve location, turbocharger size and pressure, but as a general rule of thumb, we recommend the Type RS for 100-400hp, Type R for 260-450hp and the Stiff Spring Type R for over 400hp applications. Also available in easy to install kit form for many turbocharged vehicles.
