 Valve Upgrade for VW/Audi / 1.8T / 2.2T / 2.7T / 4.2T)
034Motorsport is proud to offer our Billet Aluminum Diverter Valve for various Audi, Porsche, and Volkswagen vehicles! This high-quality, performance engineered diverter valve is designed to replace the factory plastic diverter valve, which is a common source of boost leaks. Unlike the OEM valve, which uses a fragile rubber diaphragm that is prone to failure, the 034Motorsport Diverter Valve features a high-performance spring and piston design. This means that the valve lasts much longer, and is capable of handling increased boost pressure.
Designed to be an affordable, no compromise replacement for the factory diverter valve in 1.8T, 2.2T, 2.7T, and 4.2T applications, the 034Motorsport Bypass Valve features 1" inlets and outlets.
The 034Motorsport Bypass Valve is fully serviceable and rebuildable.
