Mitsubishi Evolution Piston Kit - JE Pistons - 4G63 EVO KIT Set of 4 Pistons

The Mitsubishi Evolution Piston Kit by JE Pistons is specifically designed for the renowned 4G63 engine. This kit includes a set of four pistons, each crafted with a 3.346 in. bore and an inverted dome/dish for enhanced engine performance. Perfect for EVO models from 2001 to 2007, these pistons are engineered to handle the high demands of performance racing.

Manufactured from high-grade 2618 aluminum, the JE Pistons 4G63 EVO KIT provides the robustness and durability needed for intense racing applications. The pistons are crafted in the USA, using a proprietary Forged Side Relief (FSR) design to reduce friction, minimize power loss, and optimize performance with a reduced skirt width and a shorter wrist pin. The skirt coating enhances durability and minimizes operating noise, while the accumulator groove supports consistent power by improving ring seal and reducing ring flutter.
