Product Description

The Turbosmart TS-0203-1021 Kompact Dual Port Blow-Off Valve (BOV) is a high-performance turbocharger pressure relief valve engineered for boosted applications that require reliable boost control and improved throttle response. Designed to replace OEM bypass valves on many turbocharged engines, this dual-port BOV vents excess boost pressure both to the atmosphere and back into the intake depending on engine demand, giving a balanced mix of sound and performance.

Built from precision billet aluminum with a 20mm inlet/outlet, this valve offers greater durability and flow capacity than most stock or economy units, and includes an adjustable spring for tuning actuation characteristics. The convertible design allows you to configure for full atmospheric venting or full recirculation by using the supplied blanking plug, making it ideal for street cars, track use, and custom forced induction builds. Whether you're upgrading a stock turbo system or building a high-boost setup, the Kompact Dual Port BOV improves turbo efficiency and helps reduce compressor surge, giving smoother boost transitions and enhanced performance.
