About this part

Product Details

If you're working on a 2005-2007 Chrysler 300 with a 6.1L Hemi, these Manley Race Flo intake valves are a solid option for your engine build. They're designed for engines that see a lot of action, like those used in bracket racing, drag racing, or oval track racing, and are built to handle up to 8000 RPM.

These valves are made from stainless steel, which is a strong material that holds up well over time. The stems are chrome-plated and the tips are hardened to resist wear, especially important in high-stress engine environments. Manley also swirl-polished the areas under the head and fully machined the combustion faces. This helps improve airflow into the cylinder and can contribute to better combustion efficiency. You're getting the Race Flo shape here, which is designed to optimize flow for specific racing applications.

This set includes eight intake valves, which is what you'll need for a V8 engine. While these are recommended for alcohol engines as exhaust valves, they are built with the durability and airflow improvements that benefit any performance Hemi build.
