The JE Pistons four‑piston kit for Subaru EJ25 DOHC engines is a forged replacement set specified at 11.5:1 compression for EJ series applications. Forged in the USA from 2618 aluminum, these pistons use JE’s FSR forging to reduce skirt width and friction. The kit comes with premium wrist pins, locks and JE Pro Seal rings and includes accumulator grooves and optional skirt coating to minimize ring flutter and improve sealing under higher loads.
