Product Description

The Turbosmart TS-0205-1016 Dual Port Blow-Off Valve (BOV) is an aftermarket turbocharger pressure release upgrade engineered specifically for turbocharged Subaru Impreza WRX, WRX STI, and Forester XT models within the listed years. Its dual port design offers balanced performance: quiet, compliant operation at low boost while delivering effective pressure relief and greater sound and response at higher boost levels. This valve manages excess pressure more efficiently than stock recirculation valves, improving turbo stability and helping protect the turbocharger from compressor surge.

Constructed from high-quality billet aluminum with a black anodized finish, this direct-fit BOV installs easily using the supplied hardware and gasket. The sequential dual ports and pre-installed yellow spring (rated -22 to -20 InHg) make it ideal for stock and moderately modified Subaru turbo engines. It's a popular choice for enthusiasts looking to enhance throttle response and turbo sound during deceleration, while still providing reliable performance in street and track environments. Ensure correct vent or recirculation configuration based on your intake setup and local emissions regulations.
