Skunk2 Alpha Series Honda/Acura Stock Size B Series VTEC Valve (Standard Compression)

Starting with a one-piece forging from HNV3 martensitic steel for intake valves and EV8 austenitic steel for exhaust valves, these Skunk2 Alpha Series valves are built for strength. They undergo a proprietary heat-treatment process that makes them exceptionally durable, and feature hard chrome plating along with fully machined valve heads. The specially designed valve head profiles are key to optimizing airflow, which is something Skunk2 tests extensively in-house on the dyno and on the road to ensure you get reliable performance gains.

These are stock-size valves, meaning they fit right into your existing setup without modification, and they're designed for standard compression applications. With intake valve heads measuring 33.00mm and exhaust at 28.00mm, they offer a good balance for airflow. They're also notably lighter than stock, typically between 3-10 grams less per valve, which can help reduce valvetrain stress. This attention to material choice, heat treatment, and airflow design means you're getting a well-built component for your B Series VTEC engine.
