The Wiseco K544M87 Professional Series forged pistons are engineered specifically for high-performance Honda H22 engines, offering exceptional durability and precision for serious racers and builders. Crafted from high-strength 2618 aluminum in the USA, these pistons deliver superior tensile strength and reliability under demanding conditions. Each piston features precision ring grooves, an anti-detonation groove, and enhanced sealing capabilities that optimize combustion efficiency and power output. The ArmorGlide skirt coating reduces friction, minimizes noise, and resists seizure, ensuring smoother operation over extended periods of heavy use. Designed to withstand severe duty applications, these pistons are ideal for race engines and performance upgrades. The full machining on the crown provides precise fitment and consistency, while forced pin oiling ensures reliable lubrication of the wrist pins for long-term durability. This set includes four pistons with a 87mm bore diameter and a 31mm compression height, tailored specifically for Honda Prelude models from 1995 to 2001. The Wiseco Professional Series pistons are a vital upgrade for any performance enthusiast aiming to maximize engine output and reliability in demanding racing environments.
