Brian Crower Stainless Steel Exhaust Valves STD Size - 02-14 WRX / 04-21 STI / EJ Turbo Models

Part Number: brc BC3601-S 32.0mm Exhaust (Standard head diameter) BC 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.
