Wiseco Mitsubishi EVO X 4B11 Turbo -4.5cc 86mm Bore 8.8 CR HD Forged Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance applications. The 86mm bore size and -4.5cc dish contribute to an 8.8:1 compression ratio, making them a solid choice for boosted 4B11 engines in Mitsubishi EVO X models. Wiseco engineers these pistons with precision ring grooves, anti-detonation features, and enhanced ring sealing to ensure reliable performance under extreme conditions.

Beyond the core forging, these pistons feature an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, all critical factors when pushing an engine hard. The fully machined crown and forced pin oiling further demonstrate the attention to detail in their construction, aiming for improved durability and longevity in severe duty builds. This kit includes four pistons, ready for your performance engine build.

It's important to note that this piston kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
