Skunk2 Pro Series Honda B16A/B17A/ B18C DOHC VTEC Stage 3+ Cam Shafts

Starting with a lift of 12.70mm on the intake and 11.93mm on the exhaust, these Skunk2 Pro Series Stage 3+ camshafts are built for serious performance in your Honda B-series VTEC engine. They're designed to push your engine's powerband higher, aiming to increase peak horsepower by over 25 hp and torque by 18-22 ft-lbs. This means you'll see a noticeable boost in the mid-range and top-end, with peak power arriving around 700 rpm later than with their Pro 2+ cams, creating a broader, more usable powerband and a seamless VTEC crossover.

These aren't just any camshafts; they're manufactured from proprietary, chill-cast billet blanks that offer improved torsional strength and durability while reducing friction. Skunk2 uses advanced CNC grinding machines with cubic-boron wheels to achieve their patent-pending profiles, featuring unique lobe shapes and advanced Fast Ramp and AMAX technology. This AMAX technology maximizes the area under the lift curve without sacrificing reliability or valvetrain stability, giving you unmatched engine response from idle all the way to the 9800 rpm range they're designed for. They are ideal for heavily modified engines where every bit of performance counts.

When installing these, remember that they are intended for racing applications and are not CARB approved, so they cannot be shipped to California. For optimal performance and reliability, it's crucial to ensure your valvetrain components are in excellent condition and properly set up to handle the increased lift and duration. Refer to the manufacturer's installation instructions for specific details on valve clearance settings, which are .007 in. for intake and .008 in. for exhaust.
