The Supertech piston set for Honda K‑series 86.50mm bore contains four forged pistons with a +6.5cc dome to produce an 11.2:1 compression ratio; rings are sold separately. Manufactured to match the 86.50mm bore and chamber volume, this set provides the correct compression profile for K‑series four‑cylinder rebuilds or cylinder work that requires a modest compression increase without changing bore size.
