Brian Crower Mitsubishi 4B11T Evolution X 35mm Intake Valves

These 35mm intake valves from Brian Crower are made from a high-strength stainless steel alloy, chosen for its ability to withstand the heat and stress inside the 4B11T engine found in the Mitsubishi Lancer Evolution X models from 2008 and 2010-2015. When you're rebuilding the top end or looking to improve airflow for a performance application, valves are a critical component. Brian Crower has a solid reputation for making well-built engine parts, and these valves are designed to handle the demands of a performance engine.

The larger 35mm diameter compared to stock allows for a greater volume of air to enter the combustion chamber. This is a key factor in making more power, especially when paired with other engine modifications. The stainless steel construction helps ensure durability and resistance to wear and corrosion, even under high operating temperatures. They are designed as a direct replacement for your factory valves, making installation straightforward if you're already working on the cylinder head.

If you're tuning your Lancer Evolution X, upgrading your intake valves is a sensible step to support increased airflow demands. Ensure you have the necessary tools and a service manual for proper cylinder head disassembly and reassembly when installing these valves.
