Wiseco 2008+ Mitsubishi 4B11 EVO X 86mm Bore Std Oversize 86mm Strk 3.5cc Vol 10.5:1 - Set of 4

If you're rebuilding the engine in your 2008 and newer Mitsubishi 4B11 EVO X for serious racing or heavy-duty performance, a strong set of forged pistons is essential. These Wiseco Professional Series pistons are built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of severe duty race applications. They are forged and machined right here in the USA.

Wiseco has packed these pistons with features to ensure durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other ring seal improvements designed to handle high cylinder pressures. The fully machined crown and forced pin oiling further contribute to their robust design. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when pushing an engine hard.

This set includes four pistons, each with an 86mm bore and a 10.5:1 compression ratio, designed to work with an 86mm stroke. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in a 4B11 engine, this Wiseco set is a solid option.
