Show original supplier description
The 034Motorsport Billet Aluminum Diverter Valve is engineered as a premium replacement for the stock plastic diverter valve found in many Audi, Porsche, and Volkswagen models. Factory diverter valves are known to fail due to their fragile rubber diaphragms, leading to boost leaks. This upgrade addresses that weakness by employing a robust billet aluminum construction and a high-performance spring and piston mechanism. The design focuses on enhanced durability and the ability to manage higher boost pressures, making it ideal for tuned vehicles or those running increased boost. The valve features 1" inlets and outlets and is designed for direct replacement of the OEM unit. It is fully serviceable and rebuildable, extending its lifespan and performance. Key features include its billet aluminum construction, availability in polished aluminum or black anodized finishes, and a proven high-performance spring and piston design that ensures superior valve response and long-term durability. This diverter valve is specifically designed for 1.8T, 2.2T, 2.7T, and 4.2T applications, offering an affordable, no-compromise solution for enthusiasts seeking to eliminate boost leaks and improve engine performance.
