Skunk2's Alpha valve spring set upgrades the K-series and F-series DOHC VTEC valvetrain with dual inner and outer springs wound from super-clean chrome-silicone wire milled in Japan. Mated at a slight interference fit and tuned to differing frequencies, the springs resist valve float and hold valvetrain stability at engine speeds above 10,000 rpm. Each set covers a full head of 16 valves.
