Product Details

Denso reman starters are rebuilt with a focus on electrical integrity, wear components, and final performance validation. During remanufacturing, the armature and field coils are tested at high voltage, commutators are refinished and checked, and terminals and fasteners are replaced with copper components. The result is a starter designed to restore reliable engine cranking while supporting efficient use of recycled materials. Part number 280-4138 is a direct-fit style replacement for select Subaru Forester and Subaru Impreza vehicles equipped with the specified starter configuration.

This part cross-references Bosch SR4304X for the same application.
