JE Pistons Mitsubishi 4G63 Evolution VII-IX Forged Piston Kit – High-Performance 22mm Pin, 3.366 Inch Bore, 8.50:1 Compression, Inverted Dome/Dish, Set of 4

Description

Upgrade your Mitsubishi 4G63 engine with the JE Pistons MITSU 4G63 EVO KIT, engineered specifically for Evolution models from 2001 to 2007. Crafted from high-grade 2618 aluminum and forged in the USA, these pistons are designed to deliver exceptional durability and performance for racing or high-demand driving scenarios. Their precise engineering ensures optimal fit and function, making them an ideal choice for enthusiasts seeking reliable power gains and longevity. The set includes four pistons, each featuring a proprietary Forged Side Relief (FSR) forging design that minimizes friction and reduces power loss by decreasing skirt width and shortening wrist pins. This innovative design helps improve overall engine efficiency and responsiveness. The pistons are equipped with an accumulator groove (depending on application) to help reduce combustion pressure, which diminishes ring fluttering and enhances ring seal for consistent power output. Additionally, the skirt coating (application-dependent) reduces friction and wear on piston skirts and cylinder walls while also lowering operating noise, contributing to smoother engine operation. Each piston set comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring a comprehensive upgrade for your engine. Designed for specific engine configurations, these pistons optimize performance and durability for applications ranging from street driving to competitive racing. Manufactured entirely in the USA, JE Pistons stand for quality, precision, and proven performance, making them a trusted choice for serious automotive enthusiasts seeking to maximize their engine’s potential.
