Wiseco 2008+ Mitsubishi EVO X 4B11 -9cc 86mm Bore Piston Shelf Stock Kit

Wiseco is well-known for building strong, reliable engine components for demanding applications. This Professional Series piston kit is a prime example, designed for serious racers and builders who push their engines hard. If you're working on a 2008 or newer Mitsubishi EVO X with the 4B11 engine and need pistons that can handle severe duty, this set is built for that purpose.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for high-performance use. 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 for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and keep operation quieter, all crucial for a high-stress engine.

This kit includes four pistons, each with an 86mm bore and a -9cc dish. They are designed to fit the 4B11 engine and are intended for heavy to severe duty performance builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
