Wiseco 97-02 Mitsubishi Lancer 4G93/4G94 1.8L 81.5mm Bore .020 Size -2.5cc FT 1.190CH 8.9 Piston Kit

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle heavy to severe duty use in race builds. These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crown is fully machined, and they come with forced pin oiling to keep things well-lubricated. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which are all important factors when you're pushing an engine hard. This kit is specifically sized for an 81.5mm bore and is .020 inch undersize.

This set includes four pistons. 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.
