Manley 92-00 Acura Integra / 99-00 Honda Civic 16 Valve 33.0mm Race Flo F/F Intake Valves (Set of 8)

If you're rebuilding the top end of your 1992-2001 Acura Integra or 1999-2000 Honda Civic, these Manley Race Flo intake valves are a solid option. They're designed for engines running up to 8000 RPM, making them suitable for bracket, drag, and oval track racing applications. The 33.0mm Race Flo shape is specifically chosen to help optimize airflow into the combustion chamber.

Manley builds these intake valves from stainless steel, which is a strong material that holds up well to the heat and stress inside an engine. They also feature chrome-plated stems and hardened tips to resist wear, ensuring they last longer. The under-head area is swirl-polished and the combustion faces are fully machined. This attention to detail helps smooth the path for air entering the cylinder, which can lead to improved combustion efficiency.

This set includes eight intake valves, enough for a typical 16-valve cylinder head. While these are intake valves, Manley recommends their stainless steel exhaust valves for alcohol-fueled engines due to the demanding conditions.
