Wiseco Mitsubishi EVO X 4B11 Turbo -4.5cc 86.25mm Bore 8.8 CR HD Forged Piston Kit

If you're building a high-performance Mitsubishi EVO X with the 4B11 Turbo engine, this forged piston kit from Wiseco is designed for serious racers and builders. These pistons are made from 2618 aluminum, which offers improved tensile strength for demanding applications. They are forged and machined right here in the USA, ensuring a well-built component for your project.

Wiseco has packed these pistons with features to handle heavy to severe duty performance. You'll find precision ring grooves, an anti-detonation groove, and other features that improve ring seal. The crown is fully machined, and they include forced pin oiling to keep things lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly. This kit is intended for those who are pushing their engines hard and need components that can keep up.

This kit includes four pistons, each with an 86.25mm bore and a -4.5cc dish volume, resulting in a compression ratio of 8.8:1. The pin diameter is 0.9055 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for sport compact applications where durability and performance are critical.
