Turbo XS 2015 Subaru WRX Hybrid BOV Blow Off Valve Type XS

This is the Turbo XS Hybrid Blow Off Valve, Type XS, specifically made for the 2015 through 2019 Subaru WRX. It's designed to help your turbocharger perform better by releasing excess boost pressure when you let off the throttle. This helps prevent compressor surge, which can damage your turbo and reduce its lifespan, while also improving throttle response when you get back on the gas.

What makes this a hybrid valve is that it recirculates most of the air back into the intake system, similar to a factory bypass valve, but it also vents a small amount of air to the atmosphere. This gives you a bit of that classic blow-off valve sound without causing issues with your car's air-fuel ratio sensors, which can happen with fully atmospheric valves. The Type XS is a well-built unit from Turbo XS, a company known for its performance parts for Subarus. It's designed to fit right into your factory plumbing, making installation straightforward for someone familiar with working on their WRX.

Keep in mind that this valve is not CARB approved and cannot be shipped to California. It's a solid option for WRX owners looking to get a little more out of their turbo system and enjoy a subtle sound enhancement.
