Description
The camshaft plays an important role in opening and closing valves to enable fuel and air into the combustion chamber of your vehicle. If you are experiencing hesitation with a loss of power, jerking or shaking, more fuel consumption, or producing more emissions than usual, it could be time for a replacement. Intake and Exhaust Camshaft from Hot Cams are offered in 3 stages, with stage 1 cams offering more pulling power, stage 2 cams supplying more horsepower, and stage 3 cams providing the ultimate in rpm horsepower and over rep. Camshafts from Hot Cams are offered as a set of both intake and exhaust cams or are available separately with detailed instructions for simple and easy installation.
Additional Note
NOTE: Intake and exhaust cams are sold separately. Hot Cams #s 4165-2IN and 4166-2EX when used as a set provides increased mid-top torque and horsepower. Produces more power than the OEM cams from 6000 rpm and up with a slight loss at lower rpm. Produces more power than the stage 1 set from 8000 rpm and up. The performance will be further improved with improvements to intake and exhaust efficiency and FI remapping. Supplied with decompression mechanism.
