Skunk2 Alpha Series Honda/Acura Stock Size D Series Valve Set (Standard Compression)

Skunk2 Alpha Series valves are manufactured from HNV3 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. Alpha Series Valves feature hard chrome plating and fully machined valve heads. 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. During development, each valvetrain component is tested both on the dyno and the road. Manufactured from the best materials available in a state-of-the-art manufacturing environment ensure that Skunk2 valvetrain components provide exceptional performance, reliability, and quality.
