GrimmSpeed V2 Bypass Valve 2004-2021 STI / 2002-2007 WRX
DESCRIPTION
The GrimmSpeed V2 Bypass Valve received many upgrades such as a redesigned the internal piston to eliminate the potential failure points we saw in our V1 design. We adjusted tension of the internal spring to better suit the operating environments we've seen after further testing and development. Updated the design of the main body for a better CNC milling finish. Exchanged the internal brass piston from V1 for a lighter weight hard aluminum piston, resulting in better valve response. This valve is engineered for high performance finished in a premium gloss black or red.
WHY?
This upgraded V2 Bypass Valve by GrimmSpeed is an easy mod that you can do in just minutes. With a red or black finish this bypass valve is engineered to work better than the stock one and give your engine bay some bling.
