Product Description

The Wiseco K567M84AP is a high-performance forged piston kit designed for Honda B-series builds, especially hybrid setups like a B20B block with a B16A VTEC head. With an 84 mm bore and a +2 cc dome, this kit delivers a strong compression boost (~11.3:1) while maintaining durability and reliability.

These pistons are made from lightweight yet robust 2618 aluminum and feature strutted forging for increased structural strength. The ArmorPlating on the skirts (or ArmorGlide) reduces friction and wear under high-RPM operation. Combined with a matched ring set and 21 mm wrist pins, these pistons give you solid sealing and stable performance.

Installation requires checking piston-to-wall clearance, ring gap, and deck height. Because of the raised dome, choose an appropriate head gasket thickness to optimize compression for your specific build. This kit is ideal for high-compression, naturally aspirated, or mildly tuned B-series engines.
