This kit allows you to remove the OEM equipped by-pass valve, which is fitted as standard to remove lift off compressor surge and quieter the turbo operation.
Removing the factory BPV not only improves in gear spool times but also produces that sought-after "lift off flutter" associated with highly tuned turbos.
Also great for use in testing for isolating boost leaks as Aftermarket and OEM valves are often a source of leakage.
Commonly called, By-Pass Valve, Dump Valve, Blow-Off Valve.
