Wiseco 6627M875 1400 HD Mitsubishi EVO 8 4G63 Turbo Forged Piston -21cc

The Wiseco 6627M875 is a single forged replacement piston from Wiseco's 1400 HD (Heavy Duty) Professional Series, engineered specifically for the Mitsubishi Lancer Evolution 8 equipped with the turbocharged 4G63 engine. With an 87.5mm bore diameter and a -21cc dish crown, this piston is purpose-built for high-boost, high-output turbo applications that demand exceptional strength and heat resistance.

Wiseco's Professional Series pistons are forged and machined in the USA from 2618 high-strength aluminum alloy, a material chosen for its superior tensile strength and fatigue resistance under the extreme thermal and mechanical loads generated by forced-induction builds. The -21cc dish crown is optimized to work with the 4G63's combustion chamber geometry, supporting elevated compression and power targets typical of serious race and track builds.

Key Features:

• 87.5mm Bore Diameter — matched to 6627M875 fitment specifications
• -21cc Dish Crown — optimized for 4G63 turbo combustion geometry
• 1400 HD (Heavy Duty) Series — engineered for severe-duty and heavy race builds
• 2618 Forged Aluminum Construction — superior tensile strength over cast or hypereutectic pistons
• ArmorGlide® Skirt Coating — reduces friction, resists seizure, and quiets piston operation
• Precision Ring Grooves — machined for consistent ring seal and long-term reliability
• Engineered, Forged, and Machined in the USA — manufactured at Wiseco's Mentor, Ohio facility
• Sold as a single piston — order quantity to match your build requirement

Part number 6627M875 is also referenced with the AP suffix (6627M875AP) designating the single-unit configuration. This piston is the foundation of any serious EVO 8 4G63 high-power rebuild, delivering the durability and dimensional precision required for boosted motorsport applications.
