The JE Pistons four‑piston kit for Subaru EJ25 SOHC applications is a forged replacement set at 8.5:1 compression tailored for EJ series SOHC engines. Forged and machined in the USA from 2618 aluminum, these pistons employ JE’s FSR forging to reduce skirt width and friction. The kit includes premium wrist pins, locks and JE Pro Seal rings; accumulator grooves and optional skirt coating help curb ring flutter and sustain consistent ring sealing over time.
