Balanced Performance with That Signature Turbo Sound

If you want the benefits of a blow-off valve without going full race car all the time, the Turbosmart TS-0203-1023 Kompact Dual Port strikes that perfect balance. Designed to fit 34mm factory bypass valve ports—including setups that use BOSCH or DENSO valves and models like the 2009–2010 Subaru Legacy/Liberty—this compact unit gives you sharp turbo response with a more refined everyday driving experience. During regular cruising, it operates quietly by routing pressure back into the intake. But when you get into boost and let off the throttle, you get that crisp vent-to-atmosphere sound every turbo enthusiast lives for.

Smart Versatility in a Drop-In Design

What really makes this BOV stand out is how easily it adapts to your setup and style. Turbosmart includes a port blanking plug so you can quickly convert it into a full recirculating or full atmospheric valve, depending on how you want to run. That flexibility makes it ideal for builds that are both street-driven and track-ready. The compact housing is perfect for tight engine bays, and the durable construction ensures it can handle serious boost pressure without missing a beat. If you're looking for something that's easy to install, tuneable to your needs, and delivers both stealth and sound when you want it, this dual port BOV is a smart upgrade for any turbo setup—just not one designed for a diesel.
