Product Description

The Wiseco K622M87 is a professional-series forged piston kit designed for Honda/Acura K24 engines (using K20-type heads). With a dished crown of -21 cc, these pistons deliver a lower compression ratio (~8.7:1), making them ideal for high-performance, stroked, or mildly forced-induction builds.

Constructed from strong 2618 aluminum and featuring a strutted-forge design, these pistons provide excellent durability and rigidity under high-stress conditions. The ArmorGlide® coating on the skirts reduces friction and increases longevity, while the forced pin-oiling ensures reliable lubrication under demanding loads.

This kit includes a premium 8700XX ring set for great sealing performance. Proper installation - checking ring gaps, verifying clearances, and following torque specifications - is key to achieving long-lasting performance from your K-series build.
