Keep It Quiet Keep It Fast Keep It Clean

If you're building a sleeper or just want smooth turbo performance without all the noise, the Turbosmart Kompact Plumb Back 25mm is exactly what your setup needs. This full recirculating blow-off valve gives you all the performance benefits of a high-end BOV without the flashy sound that usually comes with it. By rerouting excess boost pressure straight back into the intake system, it keeps your airflow smooth and your presence low-key. It's perfect for daily drivers and street builds where throttle response and drivability matter just as much as reliability. Whether you’re cruising or boosting through gears, it delivers seamless transitions without attracting unwanted attention. It’s a great fit for those running factory-style BOSCH or DENSO bypass valves and even drops right into 2009-2010 Subaru Legacy and Liberty models. Compact, efficient, and built to perform, this BOV gives you the confidence to push your turbo setup without drawing a crowd.

Optimized For Recirculating Control In MAF Based Systems

The Turbosmart TS-0203-1222 Kompact Plumb Back BOV is engineered for performance-oriented turbocharged setups that rely on accurate airflow readings and stable fuel delivery. Its 25mm port size makes it a direct replacement for most factory BOSCH or DENSO bypass valves, maintaining OEM fitment while dramatically improving durability and boost management. As a full recirculating system, it ensures all excess boost pressure is redirected into the intake tract, which is essential for mass air flow sensor accuracy and stable idle in MAF-based vehicles. This makes it particularly ideal for street-driven builds where maintaining smooth transition between gears and consistent throttle behavior is crucial. Its compact design allows for hassle-free installation in space-constrained engine bays, and it fits directly onto 2009-2010 Subaru Legacy and Liberty models. Built for gasoline-powered turbo engines only, it’s not compatible with diesel applications. With improved response times, reduced compressor surge, and quiet operation, this BOV delivers serious control without compromising comfort or reliability.
