Product Details
If you're looking to fine-tune your 2015-2021 Subaru WRX's turbo system, this recirculating bypass valve from Turbo XS is a solid option. It's designed to replace the factory bypass valve, helping to manage boost pressure more effectively. This valve recirculates the excess air back into the intake system, which is quieter than a vent-to-atmosphere blow-off valve and helps maintain proper air-fuel ratios.
The Type XS valve features a billet aluminum construction for durability and a smooth, responsive operation. It uses a spring-loaded diaphragm system that's adjustable, allowing you to set the boost threshold precisely for your WRX. The red and silver finish adds a nice visual touch under the hood. This bypass valve is a popular choice for WRX owners looking for improved turbo response and a more solid feel when the turbo spools up.
Keep in mind that this bypass valve is not CARB approved and cannot be shipped to California. It's a direct replacement for the stock unit, making installation straightforward for those comfortable working on their turbo system.
