Versatile Sound and Performance in One Smart Package

If you're building a turbo setup that needs both smooth drivability and that unmistakable turbo sound when it's time to get aggressive, the Turbosmart TS-0203-1022 Dual Port Blow-Off Valve checks all the right boxes. With a dual outlet design, it vents pressure both back into the intake system and to the atmosphere. That means you get quieter, controlled operation during regular driving, but under full throttle and quick shifts, it delivers that sharp, satisfying vent-to-atmosphere sound that turbo enthusiasts love. It’s a great choice for those who want the best of both worlds—refined daily manners with the option to unleash some turbo attitude on demand.

Adaptable Design for Custom Setups and Twin-Turbos

One of the standout features of this BOV is its flexibility. It comes with a port blanking plug, allowing you to easily configure it as a full recirculating or full atmospheric valve based on your build goals or sound preferences. That adaptability makes it ideal for custom projects, street builds, or track cars. It’s also a smart choice for twin-turbo applications like the Audi S4 2.7L (B5), where you’ll need two valves for proper operation. Compact and easy to install, it works well in tight engine bays without sacrificing performance. Whether you're fine-tuning boost control or just want a responsive, reliable valve that won’t let you down, this one’s built to keep up.
