BC valves are made from premium stainless steel, fully machined and swirl polished for precision performance. Unlike stock valves, they feature a dished head design for added weight savings and increased stability at high RPM. The undercut stem above the head area also reduces weight and significantly improves air/fuel flow in and out of the combustion chamber. BC valves will help you get the most out of your high revving Civic Si motor!
