Upgrade Your Turbo Without Drawing Unwanted Attention

For performance that flies under the radar but still delivers every time you hit boost, this BOV is the perfect choice.

Recirculating Design Built For Boost Control And Consistency

The Turbosmart TS-0203-1221 Kompact Plumb Back Uni Fit 20mm Blow-Off Valve is engineered for high-performance turbocharged engines that rely on precision and stealth. Featuring a fully recirculating design, this valve redirects excess boost pressure back into the intake stream, helping to maintain consistent airflow for vehicles equipped with mass air flow (MAF) sensors. This prevents common driveability issues such as rough idle and rich fueling between shifts, making it ideal for street-driven cars and tuned builds alike. The 20mm inlet size is designed to directly replace factory BOSCH or DENSO bypass valves, and it fits seamlessly into vehicles such as the 2009-2010 Subaru Legacy and Liberty. Compact dimensions allow for easy integration into tight spaces, without compromising performance or durability. This BOV is not suitable for diesel applications and is best used in gasoline-powered turbo setups. It offers improved turbo longevity, faster response between gear changes, and greater reliability over factory components. For enthusiasts focused on smooth operation and factory-like stealth, this is a proven upgrade.
