Wiseco Mitsubishi EVO X 4B11 Turbo -14cc 87mm Bore 8.8 CR HD Forged Piston Kit

If you're building a high-performance Mitsubishi EVO X with the 4B11 turbo engine and pushing the limits, you need pistons that can handle the stress. This Wiseco forged piston kit is designed specifically for those demanding builds, offering the strength and durability required for heavy to severe duty racing applications. Each piston is forged from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when dealing with the high pressures and temperatures of a turbocharged engine.

Wiseco doesn't cut corners here. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall combustion efficiency. The piston crown is fully machined for accuracy, and they even include forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, keeping your engine running smoothly and reliably when it matters most.

This kit includes a set of four pistons, each with an 87mm bore and a -14cc dish, resulting in a compression ratio of 8.8:1. Remember, these are built for performance and are not CARB approved, so they cannot be shipped to California. If you're serious about your build and need components that can withstand the rigors of racing, this Wiseco piston kit is a solid choice.
