Skunk2 Alpha Series Valves for the Honda K20 and K24 are manufactured from HNV-3 martensitic steel (IN) and EV8 austenitic steel (EX) one-piece forgings. Each valve is heat-treated using a proprietary process for extraordinary strength and durability and then hard chrome plated to further increase strength, significantly reduce friction, and increase corrosion resistance._x000D_

Other valves may appear similar, but Only Alpha Series Valves feature specially designed valve head profiles to optimize airflow. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. Skunk2 valvetrain components provide exceptional performance, reliability, and quality and are standard-issue on each Skunk2 vehicle that we build and support._x000D_
