Wiseco Mits Turbo DISH -17cc 1.378 X 86.5 Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The -17cc dish design and 86.50 mm bore are specific to certain Mitsubishi 4G63 engines, aiming to optimize combustion chamber volume for boosted applications. This set includes four pistons, each featuring precision-machined crowns, anti-detonation grooves, and enhanced ring seal features to ensure reliable performance under severe operating conditions.

Wiseco includes their ArmorGlide skirt coating on these pistons. This coating is designed to reduce friction and resist seizure, contributing to both durability and quieter operation. The forced pin oiling feature further aids in lubrication, crucial for high-performance engines that see heavy use. These pistons are engineered and machined in the USA, reflecting a commitment to quality construction for demanding race builds.

This piston kit is intended for builders who are pushing the limits of their engines. 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.
