034Motorsport's high-quality silicone PRV (Pressure Regulating Valve) Elbow for B6 1.8T. The factory hose is a very common point of failure, and almost always rips when removing the stock PRV. Constructed from 4-ply high-temperature automotive grade silicone, will not crumble apart or rip like the factory rubber hose. This elbow fits between the PRV and metal tube running alongside the valve cover.
