About this part

Product Details

When you're rebuilding the top end of your engine, especially for performance applications, you need parts that can handle the heat and stress. What you get in this package are Manley Race Master exhaust valves, designed for engines that see a lot of action, often running up to 8000 RPM. These are specifically the exhaust valves, measuring 30.0mm, and they're built to be a solid choice for racers and serious builders.

These valves are made from stainless steel, which is a well-built material that holds up well to high temperatures. They also feature chrome stems and hard tips, adding extra durability and wear resistance where it counts. The under-head areas are swirl polished and the combustion faces are fully machined. This helps improve airflow into the cylinder and can contribute to more efficient combustion. Manley offers these in a 'Race Master' straight stem design, which is what you're looking at here, and also a 'Race Flo' shape, so you can pick what best suits your engine build. They're even recommended for alcohol-fueled engines, which run hotter and demand more from exhaust components.

These valves are a good fit for a range of vehicles, including popular models like the 2002-2006 Acura RSX Type S, the 2004-2008 Acura TSX, and many Honda models like the Civic, Accord, CR-V, and Element from the early to mid-2000s. If you're working on a performance engine build or a restoration where you want improved valve durability, these are a strong option to consider.
