Wiseco K596M86AP Forged Piston Kit Mitsubishi Lancer EVO 8 4G63 Stroker Turbo 86mm

The Wiseco K596M86AP is a forged performance piston designed for the Mitsubishi Lancer Evolution 8 equipped with the 4G63 turbocharged engine in a 100mm stroker configuration. Built from 2618 aluminum alloy using Wiseco's in-house forging process, this piston delivers superior strength and durability for high-boost, high-stress turbo applications.

This piston features Wiseco's ArmorPlating (AP) coating on the crown and wrist pin bore — an abrasion-resistant treatment that increases aluminum hardness, improves ring groove durability, prevents micro-welding of piston rings, reduces carbon buildup, and resists corrosion from detonation events. The skirt is treated with ArmorGlide anti-friction coating to minimize scuffing during break-in and reduce cylinder wall friction throughout the life of the engine.

Key Features:

• 86.00mm bore diameter — designed for standard or freshly honed 86mm cylinders
• Stroker application — engineered for 100mm stroke 4G63 builds (2.3L displacement)
• Forged from 2618 aluminum alloy for enhanced tensile strength under turbo boost
• ArmorPlating crown coating — increases hardness, fights detonation and ring micro-welding
• ArmorGlide skirt coating — reduces friction, seizure resistance, and quieter operation
• Fully machined crown with textured top face for improved combustion characteristics
• Precision ring grooves with anti-detonation groove for improved ring seal
• Forced pin oiling for enhanced wrist pin lubrication under race conditions
• Includes rings, wrist pin, and pin locks

The Wiseco K596M86AP is engineered for serious performance builders pursuing maximum power from the iconic Mitsubishi 4G63 platform. Whether building a street/strip machine or a dedicated race car, this piston kit provides the durability and precision required to withstand sustained high-boost operation.
