Zawór blow off BOV Turbosmart TS-0203-1008 Kompact Dual Port Cadillac ATS-V 2015- - TS-0203-1008 - The Kompact Dual Port Blow-Off Valve kit for the Cadillac ATS-V has been designed to improve turbo response and eliminate compressor surge, enhancing the efficiency and longevity of the ATS-V’s turbochargers, while providing that high-performance blow-off valve sound that lets everyone know just what hides under the Cadillac’s hood. The Kompact Dual Port is a 50-50 vent-to-atmosphere and recirculating valve. Its staged operation ensures enough air is recirculated back through the intake to keep the ECU happy and to ensure quiet operation at low boost, while maintaining the performance and sound of a vent-to-atmosphere blow-off valve. The Dual Port’s smart modular design also allows you to simply unscrew the vent-to-atmosphere trumpet, and replace it with the supplied blanking plug, to transform it to a full recirculating valve for quieter, under-the-radar operation. Turbosmart’s Dual Port is proof you can have the best of both worlds! Machined with precision from billet aluminum with a black anodized finish, the Kompact Dual Port is both attractive and durable, with the strength to handle all the boost you could throw at it, with zero leaks. Includes 2x Kompact Dual Port BO Vs, Cadillac-specific flange, blanking plugs and washers.
