Wiseco 2008+ Mitsubishi EVO X 4B11 -14cc 88mm Bore Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle heavy to severe duty use. If you're rebuilding the engine in your 2008 or newer Mitsubishi EVO X with the 4B11 engine, these pistons are designed to remove your limits.

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 come with forced pin oiling to keep things lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This kit includes four pistons, each with an 88mm bore and a -14cc dish. The compression height is 29.26mm, and they use a 0.9055 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
