Skunk2 Ultra Series Honda/Acura K20A/K20A2/K20Z1/K20Z3/K24A2 DOHC i-VTEC Drop In D1 Camshafts

If you're looking to get more power out of your K-series engine, especially in the mid-range and up to redline, these Skunk2 Racing Ultra Series D1 camshafts are a solid option. They're designed as a direct replacement for your stock camshafts, meaning you can install them without needing to change out your stock valve springs and retainers, which simplifies the job. These cams are built to optimize your engine's performance in the upper RPM band, moving peak horsepower and torque higher up, which also makes the VTEC crossover feel more seamless and broadens the overall powerband.

Skunk2 makes these camshafts from a forged tool steel core, which gives them increased torsional strength and improved durability. They're CNC ground to exact specifications, featuring hardened, wear-resistant lobes. The patent-pending profiles have unique lobe shapes and advanced lift and acceleration characteristics. On well-tuned, modified engines, you can expect gains of around 15-22 horsepower. They're also a great choice if you're running a turbocharged setup, as they help maintain valvetrain stability and engine response even with increased boost.

While these camshafts are designed to work with your stock valvetrain components, it's always a good idea to check the manufacturer's installation instructions for any specific recommendations regarding break-in procedures or other requirements. Keep in mind that these are not CARB approved and cannot be shipped to California.
