This Silicone Replacement PCV L-Hose runs from the suction jet pump to the intake manifold on most B5/B6 Audi A4 1.8T models produced from 1998 - 2003.

With time, the OEM rubber hose becomes very prone to cracking, causing your engine to idle poorly and resulting in check engine lights from vacuum leaks. Unlike the factory part, our replacement hose is manufactured from high temperature silicone for long life.
