Wiseco Mitsubishi 4G63 86.00 mm Bore 28.70 mm CH 1.90 CC Piston Set

If you're building a high-performance Mitsubishi 4G63 engine, this forged piston set from Wiseco is a solid choice for serious racers and builders. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. They're designed to handle heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Wiseco packs a lot of features into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to keep things lubricated. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduce friction, and operate more quietly. These aren't just pistons; they're built with custom-level performance and durability in mind.

This set includes four pistons, each with an 86.00 mm bore and a 28.70 mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in a 4G63, this Wiseco set is a well-built option.
