The JE forged piston kit for Acura K‑Series (K20/K24) is a four‑cylinder set cut for a 3.465 in. bore with an 11.50:1 compression ratio and a dome profile. Made entirely in the USA from 2618 aluminum, the kit includes JE Pro Seal rings, wrist pins and locks. JE’s Forged Side Relief forging reduces skirt width and friction while accumulator groove features and skirt coatings where applied help stabilize ring seal and reduce wear in high‑demand engines.
