Put a little zip into your Acura LS/RS/GS (Non VTEC) with Crower's original line of chilled cast cam cores. Not regrinds of stock cores, but semi finished cores specifically designed for Crower that exceed factory specs for hardness and compatibility. Like all Crower cams, these are ground in-house at Crower. No more base circle problems typical with stock regrinds. Crower has developed several performance grinds from stock replacement, high performance street/strip, to full race (drag or road). Part # 62405A
