PERRIN 02-07 Subaru WRX / 04-21 STI / 06-08 FXT Bypass/Blow Off Valve - Black

Perrin Performance is well-known for making well-built parts for Subaru vehicles, and this bypass valve is no exception. If you're looking to manage boost pressure more effectively on your 2002-2014 Subaru Impreza, WRX, or STI, this part is designed to do just that. It helps to recirculate excess boost pressure back into the intake system when you lift off the throttle, which can help protect your turbocharger and improve throttle response.

This bypass valve is constructed from aluminum and features a black finish. It's designed as a direct replacement for your factory valve, making installation straightforward. The internal diaphragm is made from silicone, which is a durable material that can handle the pressures and temperatures found in the engine bay. This updated design helps ensure consistent operation and longevity.

While this part is not CARB approved and cannot be shipped to California, it's a solid option for Subaru owners looking for improved boost management. Make sure to check the specific fitment for your WRX or STI model to ensure compatibility.
