Features: Directly replaces the al parts. It's made of a single piece of machined billet steel and being heat treated for hardness. Upgraded camshaft g ives more lift, duration and valve overlap. This also means the problematic exhaust valve lifter mechanism is no longer needed due to the Camshaft timing and valve overlap. Even without any other changes to the ECU this will give around 20% extra power.
