Product Description

The Turbosmart TS-0203-1071 Kompact Dual Port Blow-Off Valve is a performance-oriented upgrade engineered for Suzuki turbocharged 1.4 L Boosterjet engines, including the Swift, Vitara S, Vitara Sport, and SX4 S-Cross from approximately 2018 through 2021. Designed as a direct replacement for the OEM valve, this Kompact BOV features a dual port design that vents excess boost both to the atmosphere and back into the intake, delivering improved turbo response, reduced compressor surge, and enhanced durability over stock plastic valves.

Constructed from precision billet aluminum with high-temperature seals and a 28 mm high-flow design, the TS-0203-1071 holds boost more effectively and provides consistent actuation across varying driving conditions. Sequential port timing helps keep operation smooth and quiet during regular driving while offering the classic turbo blow-off sound when pushed under load. This valve is ideal for enthusiasts looking for a performance upgrade with direct replacement fitment, but note that it is intended for race or off-road use and may not be street legal in all regions.
