Upgrade your Honda or Acura K Series engine with the Skunk2 Racing Alpha Series Valve Set, designed for optimal performance and durability. Crafted from high-quality HNV3 martensitic steel for intake valves and EV8 austenitic steel for exhaust valves, each valve is one-piece forged and heat-treated through proprietary processes to ensure exceptional strength and longevity. The Alpha Series features hard chrome plating and fully machined valve heads, providing superior sealing, airflow, and stability for high-performance applications. These valves are engineered with specially designed profiles to maximize airflow efficiency, making them ideal for high-revving engines and performance builds. Skunk2 develops and rigorously tests its entire valvetrain lineup in-house, both on the dyno and on the road, to guarantee maximum performance gains, reliability, and quality. Manufactured in a state-of-the-art environment, these components are standard in Skunk2 builds and support, reflecting their reputation for excellence in automotive performance parts. The set includes 16 valves, with a stock size and standard compression, featuring a dish face on the intake valves for better airflow and combustion efficiency. Each valve measures approximately 109mm in length, with an intake head diameter of 35mm and exhaust head diameter of 30mm, ensuring a perfect fit for compatible engines. The stems are precision-machined with a thickness of around 5.48mm for intake and 5.45mm for exhaust, contributing to overall lightweight design—3 to 10 grams lighter than stock valves—resulting in reduced reciprocating mass and improved engine responsiveness. The Alpha Series valves are built from stainless-steel alloy, providing corrosion resistance and durability for demanding driving conditions. Whether you're building a high-performance street machine or a race-ready setup, these valves offer the best combination of strength, airflow optimization, and reliability for Honda and Acura K Series engines from 2002 to 2006. They are compatible with stock compression ratios and are not carburetor approved but are suitable for various high-performance modifications.
