Detailed Product Overview

The Denso 280-4359 starter motor is part of Denso’s remanufactured starter program, which restores critical electrical and mechanical components for reliable operation. The process includes high-voltage testing of the armature and field coils, refinishing of the commutator, and replacement of terminals and fasteners with copper components. This helps maintain strong cranking torque and stable electrical transfer during startup.

This part cross-references Bosch 16098 and SR4315X for the same application. It is a direct-fit style replacement for Subaru Crosstrek, Subaru Impreza, Subaru WRX, Subaru Forester, Subaru XV, and Subaru XV Crosstrek models listed below. The 280-4359 is a strong match for drivers replacing a worn starter on a Subaru Impreza manual transmission or a Subaru WRX standard transmission.

What This Starter Helps Address

• Slow or weak engine cranking
• No-start conditions caused by starter wear
