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

Starting with the intake valve's 35.00mm head diameter and the exhaust valve's 30.00mm head diameter, these Skunk2 Alpha Series valves are crafted from HNV3 martensitic steel for the intake and EV8 austenitic steel for the exhaust. This one-piece forging design is then put through a proprietary heat-treatment process, giving them extraordinary strength and durability that holds up to demanding engine conditions. They also feature hard chrome plating and fully machined valve heads for a clean finish and reliable sealing.

Beyond just strong materials, Skunk2 specifically designs the valve head profiles to optimize airflow into and out of your K-series engine. This attention to detail helps improve performance, and the valves are often 3-10 grams lighter than stock, which can contribute to better valvetrain stability at higher RPMs. Skunk2 tests these components extensively on the dyno and on the road, ensuring they perform reliably in real-world driving. They fit a range of popular Honda and Acura models, including the Civic, Accord, RSX, and TSX.

This set includes 16 valves designed for standard compression applications, making them a solid option for engine rebuilds or performance upgrades where you want improved airflow and a well-built valvetrain component.
