Featuring a plumb back system, this valve efficiently recirculates all excess pressure back into the intake system, ensuring a smooth and quiet operation ideal for enthusiasts who prefer stealthy performance upgrades without the loud compressor surge sound. Crafted with high-quality materials, this BOV delivers reliable operation and consistent boost control, making it a perfect choice for daily drivers and performance enthusiasts alike.\u003cbr\u003eThe Kompact design offers a compact footprint that fits seamlessly into your vehicle's existing setup. Its 25mm internal diameter allows for optimal airflow and responsiveness, providing immediate boost response and maintaining engine reliability. Please note that for twin-turbo applications, such as the Audi S4 2.7L (B5) from 1997-2001, two valves are required to properly manage boost pressures across both turbochargers. The valve is not CARB approved, and installation requires acknowledgment of this status. This product is suitable for a broad range of vehicles, including various models from Fiat, Ford, Lancia, Mazda, Peugeot, Porsche, Saab, Volvo, and VW, making it a versatile upgrade for many turbocharged engines.\u003cbr\u003eDesigned for ease of installation and long-term durability, the Turbosmart Kompact Plumb Back Diverter Valve ensures your turbo system maintains optimal performance and reliability. Whether upgrading your vehicle for improved response or replacing a worn-out valve, this part provides a high-performance solution that blends discreet operation with excellent boost control.
