Wiseco Mitsubishi EVO X 4B11 Turbo -14cc 86mm Bore 8.8 CR HD Forged Piston Kit

If you're building a high-performance Mitsubishi EVO X with the 4B11 turbo engine, this Wiseco forged piston kit is designed for serious racers and builders. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. The kit includes four pistons, each with an 86mm bore and a -14cc dish, resulting in a compression ratio of 8.8:1. This setup is built to handle heavy to severe duty performance builds, giving you the confidence to push your engine's limits.

Wiseco has packed these Professional Series pistons with features for both durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The piston crowns are fully machined, and they include forced pin oiling to ensure proper lubrication. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health under stress.

This kit is a solid option for anyone rebuilding their top end for racing or extreme performance. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
