Wiseco 96-07 Mitsu Evo 4-9 4G63 Asymmetric Skirt Bore 87.00mm - Size +.080 - Single Piston

This listing is for a single Wiseco forged piston, designed for the 4G63 engine found in Mitsubishi Evolution models from 1996 to 2007. This piston has a bore size of 87.00mm and is +.080 inches oversized, meaning it's intended for an engine block that has been machined to this larger diameter. It features an asymmetric skirt design and comes with a special ArmorGlide skirt coating to reduce friction and resist seizure.

Wiseco builds these pistons from 2618 aluminum, a well-known material for its strength and durability in high-performance applications. The piston crown is fully machined, and it includes precision ring grooves, an anti-detonation groove, and features for improved ring seal. The design also incorporates forced pin oiling to ensure the wrist pin stays well-lubricated under demanding conditions, making it suitable for heavy to severe duty race builds.

This piston is intended for serious racers and builders who need a robust component for their performance engine. Please note that this part is not CARB approved and cannot be shipped to California.
