GrimmSpeed Black V2 Bypass Valve 2015-2021 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.  FEATURES: Red or black finish Corrosion resistant anodized finish, available in both red and black Oversized 38mm brass piston for superior flow Precision-tuned steel spring for long life No tuning or adjustment required Single dovetail O-ring grooves with Buna-N O-rings for great oil resistance, retention, and leak free operation Swivel air fitting to aid in install and for accommodating custom setups COMPATIBILITY 2015-2021 WRX
