Manley Honda 2.2L H22A1 Exhaust Valve Kit - 31.00mm Head Dia. 106.90mm O/A Length, 0.2150in Stem

When you're rebuilding the top end of your 1993-2001 Honda Prelude's H22A1 engine, you need parts you can count on. This kit includes the exhaust valves you need to get your engine breathing right again. Each valve is built from high-quality stainless steel, chosen for its ability to withstand the heat and stress of combustion, especially if you're running alcohol fuels. The stems are chrome-plated for better wear resistance, and the under-head area is swirl-polished to help improve airflow into the cylinder.

These valves are fully machined, including the combustion face, which helps optimize how the air-fuel mixture burns. They measure 31.00mm across the head and are 106.90mm from top to tip, with a 0.2150-inch stem diameter. Manley designed these Race Series valves for engines that see a lot of action, up to about 8000 RPM, making them a solid choice for a performance rebuild.
