COMP Cams Nitrous HP cam and lifter kits are designed to work with your nitrous system to get more power from your engine. The unique intake cam lobes allow your engine cylinders to fill better for more complete combustion. While, the exhaust lobes are spread to decrease overlap and ensure maximum scavenging of your combustion chamber. The bottom line is an increased power boost from your nitrous system, without any loss of throttle response or torque in street applications.
