Introducing the Brian Cower exhaust valves, engineered to fulfill the needs of performance enthusiasts seeking top-tier engine components without breaking the bank. Our exhaust valves are meticulously crafted to enhance the performance of your Mitsubishi 4B11 Evo X, ensuring that your engine operates at its peak potential.

Designed with precision, these valves are part of a comprehensive performance package that includes stroker kits and matching camshafts, all tailored to work in harmony.

Each exhaust valve is constructed from premium heat-resistant stainless steel, providing exceptional durability and performance under extreme conditions. The innovative undercut shaft design above the head area significantly reduces weight, allowing for quicker rotation and improved throttle response. This design also optimizes airflow to and from the combustion chamber, ensuring that your engine breathes more efficiently, which translates to increased horsepower and torque.

Our valves undergo a rigorous machining process, culminating in a spin-polished finish beneath the head. This attention to detail not only enhances the aesthetic appeal but also contributes to improved performance by minimizing friction and maximizing flow characteristics.
