The Brian Crower Stage 3 Race Specification Cams for the 02-05 WRX EJ205 and 04-07 STI EJ257 are designed with a longer duration profile and added rpm potential. These Cams are intended for fully built engines with forged internals. Upgraded springs & retainers, tuning and ECU modifications are required to run stage 3 cams.
Note: Intake camshafts are setup for AVCS operation. 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 prevents oil from passing through and actuating the Active Valve Control System. These cams are not compatible with dual AVCS systems.
