What makes these valves suitable for alcohol engines?

These Manley Race Series valves are specifically recommended for exhaust valves in alcohol engines. The stainless steel construction and robust design help them withstand the unique operating conditions and potential corrosiveness associated with alcohol fuels.

What is the benefit of the swirl-polished under-head area?

The swirl-polished under-head area is a design choice that helps to smooth the airflow as it enters the combustion chamber. This can lead to improved volumetric efficiency and better overall engine performance.

Are these valves sold individually or as a set?

The product listing is for individual intake valves. If you are rebuilding your engine, you will need to order the correct quantity to match the number of intake valves in your cylinder head.

About this part

Product Details

Starting with a 34mm intake diameter and a Race Flo shape, these Manley Race Series valves are built for performance in your 1993-1997 Eagle Talon. They are crafted from high-quality stainless steel, a material chosen for its ability to withstand the heat and stress of demanding engine operation, especially when running alcohol fuels. The chrome stems and hard tips are added to increase their lifespan and resist wear over time.

Beyond the robust material, these valves feature swirl-polished under-head areas and fully machined combustion faces. This attention to detail helps optimize airflow into the cylinder and improve combustion efficiency, which can make a noticeable difference in how your engine performs. Manley designed these Race Series valves for engines that operate under 8000 RPM, making them a solid choice for bracket, drag, or oval track racing applications.

When rebuilding or upgrading the top end of your 4G63 or 4G63T engine, these intake valves are a well-built component to consider. They are designed to fit right into your specific Mitsubishi Eclipse, Lancer, or Plymouth Laser as well, covering a range of popular performance platforms.
