Product Line Details

Bosch Starter (Remanufactured) units are part of Bosch’s starter line focused on rebuilt starting components for everyday service replacement. The SR4304X follows that approach with a remanufactured construction and application-specific design for Subaru vehicles that require this starter configuration.

Detailed Description

The Bosch SR4304X starter is engineered for Subaru engines that need a counterclockwise, 12-volt starter with an attached solenoid and closed nose housing. Its aluminum nose cone and aluminum starter finish support a durable OE-style replacement profile, while the 8-tooth drive and 2-bolt mounting layout help match the original starting system design. This Bosch SR4304X starter is a practical choice for Subaru Impreza starter replacement, Subaru Forester starter replacement, and Subaru Outback starter replacement when the vehicle calls for the listed OE application.

This part cross-references Subaru OE numbers 23300AA280 and 23300AA380 for the same application.
