The JE Pistons Mitsubishi 4G63 EVO Kit is a set of four high-performance forged pistons, specifically designed for the 2001-2007 Mitsubishi Evolution VII-IX. These pistons are crafted from 2618 aluminum for exceptional tensile strength, making them ideal for demanding performance applications. The pistons feature a proprietary Forged Side Relief (FSR) design, which minimizes friction and power loss by reducing skirt width and utilizing a shorter wrist pin. A specialized skirt coating (depending on the application) reduces friction, wear, and operating noise, while an accumulator groove (also application-dependent) enhances ring seal by reducing combustion gas pressure, promoting consistent power delivery. This kit includes premium wrist pins, locks, and JE Pro Seal piston rings for a complete upgrade. The pistons have a 3.366-inch bore, 8.5:1 compression ratio, and an inverted dome/dish design for optimized performance and durability. JE Pistons has over 75 years of experience designing and manufacturing forged racing pistons, making them a trusted choice for high-performance engines in motorsports like drag racing and drifting.
