Billet Diverter (Bypass) Valve Upgrade, Aluminum, Volkswagen GTI 1.8T (1999-2005)

Original 034Motorsport product

Make: Volkswagen
Model: GTI
Year Range: 1999-2005

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.
