Wiseco - Mitsubishi, 4G63 EVO, 86.00 mm Bore, Piston

Forged from 2618 aluminum, this Wiseco piston is built for the demands of serious racing and heavy-duty builds. The 86.00 mm bore size is a key specification for performance engine work, and Wiseco machines these with precision ring grooves, anti-detonation features, and enhanced ring sealing to ensure optimal combustion control under high stress. The ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, which is notable in a performance-oriented component. The fully machined crown and forced pin oiling are further details that speak to its construction for severe duty applications. This piston is designed for Mitsubishi 4G63 EVO engines. Not CARB approved and cannot be shipped to California.
