Wiseco Mitsu Evo 4-9 86.00mm HD2 Bore - Single Piston

This listing is for a single Wiseco 4G63 EVO piston, measuring 86.00mm in bore diameter. It's designed for Mitsubishi 4G63 engines found in EVO 4-9 models, specifically for sport compact applications. This piston is built from 2618 aluminum, a material chosen for its improved tensile strength, making it suitable for demanding performance builds.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable performance under heavy use. The piston crown is fully machined, and it includes forced pin oiling to keep the wrist pin lubricated. For reduced friction and quieter operation, the piston skirts are coated with ArmorGlide, which also helps prevent seizure.

This piston is intended for severe duty performance applications. Please note that this part is not CARB approved and cannot be shipped to California.
