About this part

Product Details

If you're rebuilding the top end of your Dodge Viper's V-10 engine, especially for racing applications under 8000 RPM, these Manley Race Master intake valves are a solid choice. They're built to handle the stress of bracket, drag, and oval track racing, ensuring your engine breathes right when it matters most.

These valves are made from high-quality stainless steel, which is a strong material for engine components. They also feature chrome stems and hard tips, adding to their lifespan and resistance to wear. The under-head areas are swirl polished and the combustion faces are fully machined. This design helps optimize airflow into the cylinders, which can improve combustion efficiency. Manley offers these in a Race Master (straight stem) shape, which is what you'll find here, designed to fit specific racing engine configurations.

This set includes ten intake valves, enough for a complete V-10 engine. They are also recommended for use in alcohol-fueled engines, particularly for the exhaust side, though these are intake valves. Make sure to check the manufacturer's installation instructions for any specific requirements when installing these performance valves.
