Wiseco Mitsubishi EVO X 4B11 Turbo -4.5cc 88mm Bore 8.8 CR HD Forged Piston Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series forged piston kit is built for serious racers and builders working on a Mitsubishi 4B11 engine, like the one found in the EVO X. These pistons are designed to handle heavy to severe duty performance builds, giving you the confidence to push your engine's limits.

Each piston in this kit is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly.

This kit includes four pistons, each with an 88.00 mm bore and a -4.5cc dish volume, resulting in a compression ratio of 8.8:1. The compression height is 29.26 mm, and they use a 0.9055 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
