JE Pistons MITSU 4G63 2.3L KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This kit is specifically designed for the Mitsubishi 4G63 engine, commonly found in the Evolution VII-IX models from 2001-2007, and increases displacement to 2.3L. The material choice, 2618 aluminum, offers high tensile strength, which is crucial when you're pushing an engine hard. JE Pistons has been making forged pistons for over 75 years, and they engineer and machine these right here in the USA.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This isn't just about making them look different; it's about minimizing friction and power loss by reducing skirt width. They also use a shorter wrist pin, which further saves weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve ring seal, meaning more consistent power. Some applications also include a skirt coating to cut down on friction and wear, making the engine run quieter and last longer.

This kit includes everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. They are designed specifically for the 4G63 engine, ensuring optimized performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
