Features

Crower cams for the 02-05 EJ20 WRX and 04-07 EJ25 STI are made from new billet cores, they are not regrinds. Crower cams require zero head modification for installation in the USDM EJ20 and EJ25 cars, other than the valve springs and retainers required with some of the more aggressive grinds. Designed to suit a multitude of applications, Crower cams are available in four off-the-shelf grinds for the 02-05 WRX and the 04-07 STI, though custom grinds are available for those looking for more than these offerings provide.
