Wiseco Professional Series Honda K-Series Piston Kit - 88.0mm Bore, 1.181in CH, +10.5cc Dome (K650M88AP)

Designed for high-output Honda K-Series builds, the Wiseco Professional Series forged piston kit (K650M88AP) is engineered for serious racers and professional engine builders. These pistons are forged and machined in the USA from high-tensile 2618 aluminum alloy, specifically selected to withstand the extreme cylinder pressures and heat of heavy to severe-duty racing applications.

Each piston features Wiseco's proprietary ArmorGlide skirt coating to reduce friction and prevent seizure, alongside forced pin oiling for improved lubrication at high RPMs. The +10.5cc dome design is paired with fully machined crowns and precision-cut ring grooves to ensure a superior seal and maximum durability under load.
