Increase engine output by 10-15 horsepower and 12-16 lb-ft of torque while maintaining a factory-smooth idle and low-speed emissions with Skunk2 Tuner Series Stage 1 Camshafts. Designed as a high-performance drop-in solution for mildly modified B-series VTEC engines, these camshafts deliver a more pronounced VTEC crossover and a significant surge in the mid-to-high RPM range. These are currently the only high-performance B-series camshafts that are CARB-exempt and legal for street use.

Each camshaft is manufactured from proprietary, chill-cast billet blanks for superior torsional strength and reduced friction. Precision-ground on state-of-the-art CNC machines using cubic-boron grinding wheels, these shafts feature hardened, wear-resistant lobes designed for longevity and consistent valve timing. Developed through decades of drag and road racing experience, the Tuner Series provides a reliable power increase from 1,500 to 8,500 RPM.
