Detailed Description

Denso remanufactured starters are rebuilt with a test-and-replace process that focuses on electrical integrity and consistent operation. The armatures and field coils are high-voltage tested, commutators are refinished and checked for performance, and wear items such as bearings, brushes, and seals are replaced. The result is a reman starter engineered to deliver factory-original starting performance for Subaru WRX STI and Impreza applications. Part number 280-0387 is also referenced in the aftermarket under several cross numbers, including BBB Industries 19071 and Remy 16144, for the same application.
