Skunk2 Racing Alpha Series Valves
Skunk2 Racing Alpha Series valves are offered in standard and high-compression versions. They are manufactured from HNV-3 martensitic steel (intake) and EV8 austenitic steel (exhaust) 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, reduce friction, and increase corrosion resistance. Other valves may appear similar, but only Skunk2 Racing Alpha Series valves feature specially designed valve head profiles to optimize airflow. Choose a set for your vehicle.
Features:
* Stainless steel alloy construction
* 3 to 10g lighter than stock
* Ensures optimum sealing, airflow, and stability
* Race and dyno tested
* Fully machined valve heads
