Brian Crower BC3041B - Honda/Acura K20A2/K20A/K20Z3 Black Nitride Exhaust Valves (30mm / STD) - set/8

BC black nitride valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel material to insure reliability with high boost and/or high rpm applications. The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head.
