Wiseco Mitsubishi 4G93 81.99mm Std Bore 1.190in CH -2.50 Dome Dish - Single Piston

Crafted from 2618 aluminum, these Wiseco pistons are forged and machined in the USA to offer improved tensile strength for demanding engine builds. The -2.50 dome dish design is specific to certain engine configurations, and the 81.99mm standard bore size ensures a precise fit for your Mitsubishi 4G93 engine. These pistons are intended for sport compact applications where durability under heavy to severe duty conditions is a priority.

Wiseco has included several features to enhance performance and longevity. Precision ring grooves, anti-detonation grooves, and additional ring seal features work together to improve compression. The piston crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pin lubricated. Additionally, an ArmorGlide skirt coating is applied to reduce friction, minimize wear, and contribute to quieter operation, making these pistons a solid option for serious racers and builders looking for robust engine components.
