The Manley Performance Platinum Series piston is a high-performance automotive component designed for Mitsubishi engines, specifically for 1995-1999 models with a 4G64 block and 4G63 head. Crafted from 2618 alloy forgings, these pistons offer exceptional strength and durability for demanding applications. They feature proven cam and barrel skirt profiles, which enhance stability and reduce piston slap under high loads. The inclusion of tool steel wrist pins ensures reliable connection to the connecting rods, while moly skirt coatings on select part numbers reduce friction and wear. This combination of materials and design elements delivers superior performance, improved combustion efficiency, and longevity for tuned or high-performance engines.
This piston is a direct replacement for 1995-1999 Mitsubishi models equipped with the specified engine configuration, making it suitable for street, track, or performance applications. It is designed as a single, oversize bore component (+.5mm) with an 8.5:1 compression ratio, ideal for engine rebuilds or upgrades seeking increased displacement and power. Installation involves standard piston fitting procedures, and it is intended for use in engines with compatible bore sizes and specifications. This piston provides a reliable upgrade for enthusiasts and professional tuners aiming for enhanced engine performance and durability in Mitsubishi 4G64/4G63 applications.
