Product Description

The Turbosmart TS-0205-1010 Dual Port Blow-Off Valve is a high-performance turbocharger pressure relief upgrade designed specifically for select Subaru and Mazda turbocharged models. Featuring Turbosmart's Boost-Balance technology and a positive-seal 38 mm piston, this blow-off valve provides quiet recirculation at partial throttle while delivering significant vent-to-atmosphere flow when needed. Its dual port design helps maintain turbo stability, reduce compressor surge, and improve throttle response across a variety of boost levels - making it ideal for both street and tuned applications.

Constructed with billet aluminum and finished in black anodize, the TS-0205-1010 mounts via a vehicle-specific flange for straightforward installation on compatible Subaru Impreza WRX, Forester XT, Legacy/Liberty GT and Mazda Mazdaspeed and CX-7 platforms. This valve supports increased airflow requirements for modified turbo systems and helps the engine breathe more efficiently under dynamic driving conditions. Always check local compliance and ensure the correct vacuum routing and intake configuration for optimal performance.
