BYPASS VALVE,034 BLACK034MOTO

034Motorsport Billet Diverter (Bypass) Valve Upgrade BLACK finish for Audi/Volkswagen 1.8T, 2.2T, 2.7T, 4.2T.

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 valves, which use 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. The 034Motorsport Bypass Valve is fully serviceable and rebuildable.
