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

If you're rebuilding the top end of your 1990-2001 Acura Integra or a compatible Honda Civic, this Skunk2 Ultra Series valve set is built for the job. These are stock-size valves designed for B Series VTEC engines running standard compression ratios. They replace your worn-out valves with components made from strong, heat-treated martensitic steel for the intake and austenitic steel for the exhaust, materials chosen for their resistance to high temperatures and corrosion.

Skunk2 puts a proprietary heat-treating process on these valves to give them exceptional strength. Each valve also gets a Chromium Nitride coating applied through physical vapor deposition. This coating is tough, improving wear resistance and reducing friction between the valve stem and guide, which is crucial for engines that run hot. Skunk2 tests these valvetrain components extensively on the dyno and in real-world driving to ensure they perform reliably.

This set includes 16 valves, enough for a full engine rebuild. The intake valves measure 33mm and the exhaust valves are 28mm, keeping them at stock size for straightforward installation in your B Series VTEC engine.
