If you're looking for a Blow Off Valve that not only delivers a unique high pitched blow off sound, but also good looks under the hood, and the ability to hold high levels of boost, we highly recommend the GReddy Type RS Blow Off Valve. The GReddy Blow Off Valve is designed with a specially designed spring that can hold boost without being too stiff, and offers a generous 40mm valve to ensure proper blow off.
Like loud blow off valves? The GReddy RS Blow Off Valve offers a unique horn that has 8 specially designed ports that amplify the surrounding air creating a loud distinct GReddy sound. If you have an older GReddy Type S blow off valve, this Type RS will work with the standard GReddy flange.
This GReddy Blow off valve is designed to be vented to atmosphere, which works fine on cars with MAP. For those of you with MAF or a Mass Air Flow Sensor, GReddy offers adapters so you can route your blow off valve back into your intake.
