Product Description

The TurboXS W15-XS-HYB Hybrid Blow Off Valve is a direct upgrade for 2015-2021 Subaru WRX vehicles, replacing the restrictive factory bypass valve with a performance-oriented unit that vents partially to atmosphere and partially back to the intake for "the best of both worlds." This hybrid design gives you an engaging turbo sound under boost without being excessively loud during normal driving, making it ideal for enthusiasts who want improved performance and sound balance.

Built on TurboXS's versatile "XS" platform, the W15-XS-HYB is modular - you can convert it to a full vent-to-atmosphere blow off by adding specific outlets and recirculating hose plugs (sold separately). The kit includes everything needed for a direct replacement installation, including vacuum hose, fittings, and hardware, and fits most factory WRX setups. This valve enhances throttle response and adds a satisfying blow-off sound while maintaining smooth daily drivability.
