Show original supplier description
It addresses a common failure point by replacing the OEM valve's fragile rubber diaphragm with a robust billet aluminum construction. This upgrade features a high-performance spring and piston design, ensuring greater durability and the capacity to handle increased boost pressure, making it ideal for tuned and high-boost applications. It includes 1-inch inlets and outlets and is available in polished aluminum or black anodized finishes. The construction utilizes billet aluminum, and the valve is both fully serviceable and rebuildable, offering long-term performance and reliability. This diverter valve is compatible with a wide array of Audi and Volkswagen models, including various Audi A4, A6, S4, TT, and RS4 variants, as well as VW Golf, GTI, Jetta, Passat, and Beetle models, primarily from the late 1990s through the mid-2000s, depending on the specific engine and chassis. It is sold individually.
