Description
B18A/B B20B/Z
The stage 4 camshaft from Rocket Motorsports is a great upgrade for any mid level B series build. Fantastic for hot street cars, largest grind available using OEM core. Offering 19% more intake duration, 7% more intake valve lift, and 10% more exhaust valve duration, and 10% more exhaust lift. Very Noticeable power gains when placed against P75 camshaft. Upgraded valve springs ARE REQUIRED
