Replace or restore your Subaru’s engine management with this genuine JDM OEM ECU, part number 22611AG573, designed for the Subaru Forester SG5 platform. Imported directly from Japan and sold by J-Spec Auto Sports Inc., this factory engine control unit delivers correct fueling, ignition timing, and drivability exactly as Subaru intended.

This OEM Forester SG5 ECU is the proper solution for replacing a failed or damaged computer, completing a JDM engine swap, or maintaining a factory-correct setup. Unlike aftermarket or mismatched ECUs, this unit ensures smooth idle, reliable cold starts, and proper sensor communication when paired with the correct wiring harness and engine configuration.

JDM ECUs are highly sought after due to their origin from low-mileage Japanese vehicles, where strict inspection laws often result in cleaner, better-preserved electronics. Each ECU sold by J-Spec Auto Sports is tested and verified for functionality and authenticity, so you can buy with confidence knowing you’re receiving a genuine Subaru component—not a clone or reflashed unit.

As SG5 parts continue to become harder to source, OEM ECUs like 22611AG573 are increasingly rare. Whether you’re a repair shop, enthusiast, or restorer, this engine computer is an essential piece for reliable operation and long-term ownership.
