Manley 92-00 Acura Integra / 99-00 Honda Civic 16 Valve 28.0mm Race Flo Exhaust Valve (Single Valve)

If you're rebuilding the top end of your 1992-2001 Acura Integra, especially for racing applications under 8000 RPM, these Manley Race Flo exhaust valves are a solid choice. They are designed to handle the heat and stress of demanding engine builds, helping to ensure your engine breathes efficiently.

These valves are made from stainless steel, which is a strong material that holds up well over time. The stems are chrome-plated and have hard tips, adding extra wear resistance where it counts. The under-head area is swirl-polished and the combustion face is machined, which helps improve airflow into the cylinder and can contribute to better combustion. Manley offers different shapes, and this is the Race Flo style, which is often chosen for specific airflow characteristics in racing engines.

These are particularly recommended for exhaust valves in alcohol-fueled engines, where they can provide reliable performance. If you're working on a performance engine build for drag, bracket, or oval track racing, these valves are built to meet those needs.
