Wiseco Mitsubishi EVO X 4B11 Turbo -9cc 86.75mm Bore 8.8 CR HD Forged Piston Kit

This kit includes four Wiseco forged pistons, designed specifically for the Mitsubishi 4B11 turbo engine found in the EVO X. These pistons are built to handle the demands of serious racing and performance builds, offering a significant upgrade over stock components. With a bore size of 86.75mm and a compression ratio of 8.8:1, they are engineered for engines that push the limits.

Crafted from 2618 aluminum in the USA, these pistons are forged for improved tensile strength, making them well-suited for heavy to severe duty applications. They feature precision ring grooves, anti-detonation grooves, and additional features designed to enhance ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to ensure proper lubrication. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation.

These pistons are intended for builders who are serious about performance and durability. It's important to note that this kit is not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed instructions for proper fitment and assembly procedures.
