Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, and this Professional Series piston set is a prime example of their commitment to performance builds. If you're working on a 1993-1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser, or a 2003-2006 Mitsubishi Lancer and aiming for serious power, especially with E85 fuel, this kit is built to handle it. These pistons are designed to replace your stock ones and are specifically made for the 4G64 engine block when using 4G63 cylinder heads, with a 10.5:1 compression ratio suitable for E85 fuel.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding applications. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal, ensuring efficient combustion and durability under stress. The crown of each piston is fully machined, and they come with forced pin oiling to keep the wrist pins lubricated. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. This kit is designed and built to withstand heavy to severe duty performance applications, giving you the confidence to push your engine's limits.

This set includes four pistons, each with an 85.50 mm bore and a 35.00 mm compression height. The pin diameter is 0.8661 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
