Brian Crower Mitsubishi 4B11T Evolution X 29mm Exhaust Valves

These 29mm exhaust valves from Brian Crower are built for the 4B11T engine found in the Mitsubishi Lancer. When you're rebuilding the top end or looking to improve airflow for more power, valves are a critical component. These are designed to handle the demands of a performance engine, ensuring reliable operation under higher temperatures and pressures.

Brian Crower uses a specific material choice for these valves, a hardened steel that's known for its durability and resistance to wear, especially in the high-heat environment of the exhaust port. The 29mm diameter is a direct replacement for the stock size, meaning they'll fit right into your existing valve seats without modification, making installation more straightforward. This attention to material and size detail helps ensure consistent performance and longevity for your engine.

If you're working on your Evolution X's engine, these Brian Crower exhaust valves are a solid option to consider for your build. They are designed to work with the specific characteristics of the 4B11T, helping to maintain proper sealing and efficient exhaust gas flow.
