Product Description

Go Fast Bits' Mach 1 Blowoff Valve will outperform whatever stock valve it replaces.  Turbo lag is reduced greatly by up to 30% in between shifts due to Go Fast Bits' quick reacting blowoff valve technology.  The Mach 1 is considered one the louder blowoff valves out of Go Fast Bits' lineup.  You will definitely be heard outside of the car with this blowoff valve.  With this Mach 1 Dual Port, you'll be able to run a full vent to atmosphere setting or a full recirculation setting and any ratio in between.  Many different Go Fast Bits fittings and adapter variations are able to be used with this blowoff valve for different hoses and vehicle fitments.

    This thing is awesome, ive had it for a couple weeks now and I absolutely love it, I have it set to full vta and no issues with my ms3, the bias venting feature is definitely worth the extra cash over those cheaper factory replacement bpv, GET ONE, YOU WONT REGRET IT!!!!!
