The JE Pistons four‑piston kit for Subaru EJ25 SOHC engines is a forged replacement set at 8.5:1 compression for EJ series SOHC applications. Made in the USA from 2618 aluminum, these pistons use JE’s FSR forging to minimize skirt width and friction. The kit includes high‑quality wrist pins, locks and JE Pro Seal rings, and offers accumulator grooves and optional skirt coating to reduce ring flutter and improve long‑term sealing under varied operating conditions.
