About this part

Product Details

If you're rebuilding the top end of your 2002-2006 Acura RSX Type S, or a compatible Honda engine like the Accord, Civic, or CR-V, these Manley Race Master intake valves are a solid choice. They're built for engines that see a lot of action, especially those running up to 8000 RPM, making them a popular option for racers and serious builders.

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 from valve guides and rocker arms. Manley also swirl polishes the area under the head and fully machines the combustion face. This helps improve airflow into the cylinder, which can make a noticeable difference in how your engine performs. They also offer a straight stem design, known as Race Master, which is what you're looking at here.

These are specifically intake valves, and they're a good fit for a range of popular Honda and Acura 2.0L DOHC i-VTEC engines. If you're working on a performance build or a thorough engine overhaul, these well-built valves are designed to handle the demands you'll put on them.
