About this part

Product Details

If you're rebuilding the top end of your 1992-2000 Honda Civic with the 1.6L SOHC engine, you'll want to make sure your new valves can handle the heat and stress. These Manley Race Flo exhaust valves are built for engines that see a lot of action, especially those running up to 8000 RPM.

Manley makes these valves from a strong stainless steel, which is a big deal for exhaust valves because they get really hot. They've also added chrome stems and hard tips to help them last longer and resist wear, even with frequent use. The under-head area is swirl polished to help air move more smoothly, and the combustion face is machined to help with airflow and make sure the fuel burns efficiently. This particular valve is the Race Flo shape, which is designed to optimize airflow in specific racing engine setups.

These valves are also a recommended choice for exhaust valves in alcohol-fueled engines, which run hotter and demand more from components. If you're building a performance engine for drag racing, bracket racing, or oval tracks, these are a solid option to consider for reliable performance.
