About this part

Product Details

Manley Performance has a solid reputation for making tough engine parts, especially for racing applications. These Race Master exhaust valves are built for your Ford 2.3L EcoBoost engine, designed to handle the heat and stress that come with performance driving. They're a step up from stock, especially if you're pushing your engine hard.

These valves are made from stainless steel, which is a strong choice for exhaust components because it holds up well to high temperatures. The stems are chromed and have hard tips, adding extra durability where it counts. You'll also notice the swirl polished area under the head and the fully machined faces; these details help improve how air moves through the engine, which can make a difference in how efficiently it runs. Manley offers different shapes, and these are the 'Race Master' straight stem type, which is a popular choice for many racing setups, particularly for alcohol-fueled engines where exhaust valves need to be extra reliable.

If you're rebuilding the top end of your Ford 2.3L EcoBoost and looking for exhaust valves that can take a beating, these are a well-built option to consider. They're made to work well under 8000 RPM, so they're ready for more than just daily driving.
