Gain an extra 15-20 hp and retain your factory idle and low-speed emissions with Skunk2’s Tuner Series Stage 2 Camshafts, our introductory line of high-performance camshafts for Honda’s H22/ F20B VTEC engines. Tuner Series Stage 2 Camshafts are designed to optimize horsepower and torque on mildly modified engines. As a result, VTEC crossover is dramatic, allowing for that classic primary-to-secondary surge. What’s more, Tuner Series Stage 2 Camshafts are based off of profiles we used on Honda Prelude Pace Cars that were then modified for street use. No other line of high-performance camshafts even comes close to Skunk2’s Tuner Series.
