Product Details

Denso reman starters are rebuilt with a test-and-replace process focused on electrical integrity and consistent cranking output. The armatures and field coils are high-voltage tested, commutators are refinished, and worn terminals and fasteners are replaced with copper components. For Mazda 6 starter replacement and Mazda CX-9 starter motor service, part number 280-4329 provides an OE-style remanufactured solution that matches the listed 12-volt, 1.6 kW, counterclockwise configuration.

This part cross-references BBB Industries 19128 and Lester 19128 for the same application.
