The Camshaft Adjuster (Intake Camshaft Sprocket / VVT Gear) with OEM number 03H109087A is a verified direct-fit replacement for the AUDI Q7 4L (2006-2009), as well as Volkswagen Touareg (2003-2010, 3.6L VR6) and Volkswagen Passat CC (2008-2016, 3.6L VR6), all equipped with the 3.6L VR6 naturally aspirated engine (EA837 series).
