Skunk2's Fine calibrating products and accessories, like its Cam Seal Black Series for the fits HON B16, B17, B18, B20, DOHC D16, F20B, H22, and H23 engines, help put the finishing touches on your vehicle. Consistent with Skunk2's heritage and high-performance parts manufacturing practices, each Cam Seal is precision CNC machined from high-quality, 6061 billet aluminum and features a durable, anodized finish. Unlike Factory cam seals, Skunk2 Cam Seals feature three o-rings for a positive seal and a precise fit. Each Cam Seal also features a -etched Skunk2 Track logo for the ultimate finishing touch.
