The Supertech piston set for Honda K24 series with a K20 head includes four forged pistons sized to an 87.0mm bore and a +4.5cc dome to reach a 12.5:1 compression ratio; rings are excluded. These pistons provide the specified crown volume and fitment for K24/K20 head assemblies, useful when exact piston geometry is required to obtain the targeted compression in four‑cylinder rebuilds.
