The Skunk2 Tuner Stage 3 Camshafts are engineered for serious performance in Honda K-Series VTEC engines, including K20A, K20A2, K20Z1, K20Z3, and K24A2 configurations using 3-lobe VTEC systems. Delivering gains of 30–35 horsepower with strong mid-range torque, these camshafts are ideal for heavily modified builds targeting high output while retaining acceptable drivability. Perfect for street cars with race-ready setups or entry-level drag cars, these cams are designed for use with upgraded valvetrain components and proper tuning.

Stage 3 cams offer dramatic gains when paired with supporting mods like high-compression pistons, ported cylinder heads, large headers, and intake manifolds. Installation should be handled by experienced professionals, ensuring precise degreeing and critical clearance checks for maximum reliability and performance.
