The JE Pistons four‑piston kit for Subaru EJ25 DOHC engines is a forged replacement set at 11.5:1 compression tailored for EJ series applications. Made in the USA from 2618 aluminum, these pistons employ JE’s Forged Side Relief design to minimize skirt width and friction. Included hardware comprises high‑quality wrist pins, locks and JE Pro Seal rings; accumulator grooves and optional skirt coating help reduce combustion gas pressure at the rings and limit wear.
