Wiseco Mitsubishi EVO X 4B11 Turbo -8cc 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 builds on your Mitsubishi 4B11 Turbo engine. The -8cc dish combined with an 86mm bore and a 33.25mm compression height results in a robust 8.8:1 compression ratio, a solid choice for boosted applications where durability is key.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable operation under extreme conditions. The crown is fully machined, and forced pin oiling helps keep the wrist pins lubricated. For added durability and reduced friction, the piston skirts are treated with an ArmorGlide coating, which also helps to quiet operation and resist seizure.

This kit includes four pistons, designed to withstand severe duty performance applications. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
