The Mitsubishi Evolution Piston Set - JE Pistons - 4B11T 86.5mm Bore Custom - '07-'15 is engineered for high-demand performance applications. This piston set is crafted specifically for the Mitsubishi 4B11T engine, ensuring optimal fit and performance for your vehicle.

Built from 2618 aluminum in the USA, this piston set provides exceptional tensile strength necessary for both street and racing conditions. The unique Forged Side Relief (FSR) design minimizes friction and power loss by reducing the skirt width, and a shorter wrist pin saves additional weight. With performance and durability in mind, each component is precisely designed for specific engine applications. Depending on the application, a skirt coating reduces friction, wear, and operating noise, while an accumulator groove helps manage pressure from combustion gases to improve ring seal and power consistency.
