Skunk2 Ultra Series Honda/Acura K20A3 & K24A1/ A3/ A4/ A8 DOHC i-VTEC Stage 4 Cam Shafts

If you're looking to get the most out of your modified K-series engine, especially for track days or serious street performance, these Skunk2 Racing Stage 4 camshafts are a significant upgrade. They are specifically designed for the K20A3 and K24A DOHC i-VTEC engines found in vehicles like the 2006-2011 Honda Civic, aiming to push your powerband higher into the RPM range for improved mid-range and top-end horsepower and torque. This means a broader, more usable powerband, especially when your VTEC system engages.

These aren't just any camshafts; they are built from proprietary forged tool steel cores for increased torsional strength and durability. Skunk2 uses advanced CNC grinding machines with cubic-boron wheels to achieve precise profiles, featuring hardened, wear-resistant lobes. The patent-pending lobe shapes, combined with their Fast Ramp and AMAX profile technology, are engineered to increase overall performance and provide unmatched engine response from idle all the way to redline. They are also a popular choice for high-output, turbocharged K-series builds where valvetrain stability is crucial.

This set includes two camshafts, designed for a seamless VTEC crossover and maximum power across the entire RPM range. Keep in mind that these camshafts are intended for heavily modified engines and are not CARB approved, meaning they cannot be shipped to California. For optimal performance and reliability, it's always recommended to consult the manufacturer's installation instructions and ensure your valvetrain components are up to the task.
