Description

The Wiseco K634M875 is a high-performance forged piston kit designed for Honda K24A series engines utilizing a K20 cylinder head swap. These pistons feature a +5cc dome volume and a 12.5:1 compression ratio with an 87.5mm bore, ideal for custom-built K-series engines. Specifically, K24A4 and K24A8 blocks require aftermarket pistons like this kit to prevent valve-to-piston contact when a K20 cylinder head is installed. This kit is suitable for enthusiasts and racers looking to build a high-horsepower K-series engine with a K20 head conversion.
