Skunk2 Ultra Series Stage 2 Camshafts for Honda and Acura K-Series DOHC i-VTEC Engines

The Skunk2 Ultra Series Stage 2 Camshafts, engineered to deliver the highest power gains in the aftermarket. These high-lift racing camshafts push horsepower and torque to new levels, with dyno-proven increases of up to 80 hp, while maintaining valvetrain stability and sharp throttle response across the entire RPM range. Built for serious enthusiasts building high-output setups, they outperform stock cams and competing profiles by maximizing mid-range pull and top-end rush, shifting peak power higher in the rev band for a seamless VTEC engagement and the widest usable powerband available.

Why These Camshafts Stand Out for Your Build

Skunk2's Ultra Series sets the benchmark for K-series upgrades, with lobe shapes that generate more torque from low RPMs through redline compared to factory or lesser aftermarket options. The revolutionary acceleration rates ensure crisp idle quality and instant power delivery, making them the clear pick for track days, drag strips, or street-stripped machines chasing maximum output. Install them in your RSX, Civic Si, or TSX, pair with supporting mods like ported heads and larger throttle bodies, and experience gains that leave competitors in the dust backed by decades of motorsport testing.
