This is the solution for the factory Positive Crank Ventilation Valve which fails commonly on the VW AG 2.0 TFSI Engines. The Billet Adapter is a direct replacement for the faulty plastic factory valve which causes unstable idle, check engine light, power loss, boost leak, and high fuel consumption. This adapter comes pre-assembled with the required barb to clip the factory block breather hose.
PCV Adapter is constructed by billet aluminum and hard anodized with a color that increases surface hardness and provides a corrosion-resistant film on the aluminum.
