Installation Notes and Tips

Verify the vehicle’s starter rotation, voltage, and OE reference before installation. Confirm the application against the Subaru Forester, Impreza, or WRX model year listed for your vehicle, and inspect battery condition, cables, and ground connections during replacement. A weak battery or corroded connection can mimic starter failure.
