About this part

Product Details

If you're rebuilding the top end of your K20A2 engine, these Manley Race Flo intake valves are a solid option. They're designed for the 2.0L DOHC i-VTEC engines found in a range of vehicles, including the Acura RSX, Honda Civic, and Accord. These valves are built to handle the demands of performance applications, offering improved airflow and durability over stock components.

Manley constructs these Race Flo valves from high-quality stainless steel, which is a strong material for engine components. The stems are chrome-plated and feature hard tips to resist wear, while the under-head areas are swirl-polished to help smooth airflow into the combustion chamber. The fully machined combustion faces also contribute to better airflow and combustion efficiency. These are a popular choice for racers and performance enthusiasts looking for a well-built valve that fits right.

For engines running on alcohol fuels, Manley specifically recommends their exhaust valves from this series, but these intake valves are still a great choice for gasoline applications. When you're putting your engine back together, having well-made valves like these can make a noticeable difference in performance and longevity.
