The Skunk2 Tuner Series Drop-In D1 camshafts are a direct-replacement cam set for K-series Honda engines that yields measurable mid- and top-end gains with no drivability loss. Tuner Series cams deliver roughly 12–15 hp in typical applications and are CNC ground from high-quality cores, allowing compatibility with stock valve springs and retainers for a simple performance upgrade that improves throttle response and power across the rev range.
