JE Pistons MITSU EVO V11-IX KIT Set of 4 Pistons

If you're rebuilding the engine in your Mitsubishi Lancer Evolution VII, VIII, or IX for serious performance, a set of forged pistons like these from JE Pistons is a critical component. These pistons are designed to handle the increased stress and heat that come with modified or high-performance engines, ensuring reliability when you push your car hard.

JE Pistons has been making performance pistons for a long time, and they build these specifically for the 4G63 engine found in your Evo. They're forged from 2618 aluminum right here in the USA, which gives them the strong tensile strength needed for demanding applications. This set includes a flat-top design with a 3.346-inch bore and a 10.00:1 compression ratio, optimized for performance. You'll also get high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, all designed to work together for a solid seal and reduced friction. Features like their proprietary Forged Side Relief (FSR) design and an accumulator groove (depending on application) help minimize friction and improve combustion gas management, leading to better power delivery and durability.

This kit is designed as a direct replacement for your stock pistons, making installation more straightforward. Keep in mind these are not CARB approved and cannot be shipped to California. For a high-performance engine build, these JE Pistons offer a well-built foundation for power and reliability.
