The Supertech piston set for Honda K engines with an 86.02mm bore and 1.181in compression height includes four forged pistons with an +11cc dome to achieve a 12.0:1 compression ratio; rings are not included. These pistons are produced to the specific bore and compression height for K‑series four‑cylinder applications where exact piston geometry and chamber volume determine final compression.
