Manufactured exclusively from super-clean, chrome-silicone wire milled in Japan, Skunk2’s Tuner Series Valve Springs for Honda’s B-series VTEC engines are a product of the company’s years of racing and engine building experiences. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Tuner Series Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm.
