The above cams WILL WORK with AVCS. If running non AVCS setup is desired, you must install the four set screws (located in a plastic bag attached to the cam bag) in the front of each intake cam (dowel pin side) using a 2.5mm Allen wrench and LocTite. This will not allow oil to actuate the Active Valve Control System.
These cams do not fit the 2008-up STi with dual AVCS. Camshafts designed for Stage 3, forced induction applications.Lope at idle, requires aftermarket valve spring and tuning.
