This Wiseco Piston Kit is designed to fit Mitsubishi 4G63 7 Bolt Engines. These Pistons feature Wiseco’s ArmorGlide® Skirt Coating for reduced friction.
The Piston Rings feature a Gas Nitrided Top Ring that works very well with Turbocharged Engines and a Napier 2nd Ring for Excellent Oil Control.These Pistons feature Wiseco’s ArmorGlide® Skirt Coating for reduced friction and Wiseco’s Armour Plating Finishing Process. The Armour Plating drastically strengthens the Piston Material, making it harder the hotter it gets. This helps resist any possible detonation and also helps the Piston Rings from Micro Welding under extreme temperatures.
