Wiseco Mitsubishi EVO X 4B11 Turbo -9cc 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 Mitsubishi's 4B11 Turbo engine, commonly found in the EVO X. If you're rebuilding the top end of your engine for serious racing or heavy-duty use, these pistons are designed to handle the stress.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. 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 to keep things lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction and noise, and resists seizure. This kit is designed to withstand heavy to severe duty performance applications.

This kit includes four pistons, each with an 88mm bore and a 29.26mm compression height. The pin diameter is 0.9055 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.
