EJ257 / EJ255 CAMSHAFTS
EJ257 / EJ255 CAMSHAFTS A series of low-volume versions with even greater power and grip were built by Subaru's in-house modifier, Subaru Tecnica International (STi). STi versions of the Impreza, which produced 280 PS (206 kW) from new, are often raced, largely unmodified, in the Group N class in various rally championships to great success. Introduced in 1994, the STi has proven to be a very popular high-performance machine in the Japanese domestic market. Introduced to the United States in 2004, the US model STi features the larger displacement 2.5L (EJ257) that features AVCS. These camshafts will also fit the 2006-2007 GDF/GDB/GDG WRX and STi Impreza (also known as the V9 or "Hawk Eye") in the UK.

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 will not allow oil to actuate the Active Valve Control System. These cams do not fit the 2008-up STi with dual AVCS.
EJ257 / EJ205 Adjustable Cam Gears
BC adjustable cam gears deliver the easiest way to dial in more horsepower and/or torque without getting underneath the valve cover, disassembling the engine or dealing with onboard electronics. BC gears are CNC machined from aerospace grade, 6061-T6 billet aluminum for ultimate tensile strength. Easy to read, laser etched face features micrometer style markings for precise adjustment (up to 10 degrees in each direction) and quick tunability. Each hub is held down by six Grade-8 hex bolts for maximum clamping ability. Hard anodized finish prevents premature surface wear.
