Product Details

This BBB Industries REMAN ALTERNATOR is engineered around the original Mitsubishi-style charging system used in Subaru Impreza, Subaru Forester, and Saab 9-2X applications. Part number 11058 is a remanufactured alternator with a conventional pulley, internal regulator, and serpentine belt drive, making it a direct-match service part for vehicles that require a 90-amp output. This part cross-references Mitsubishi-style applications such as A2TG0391 and A2TG1891 for the same application.

Compatible With 2004-2011 Subaru Impreza, N/A; 2006-2010 Subaru Forester, N/A; and 2006 Saab 9-2X, N/A. The BBB Industries 11058 alternator is a practical replacement when the charging system needs to be restored to proper operating condition on these platforms.

Common Issues This Part May Address

• Battery warning light caused by alternator output loss
• Low charging voltage during driving or idle
• Dim lights or electrical instability from weak system voltage
• Battery drain after the engine is running
• Charging-system noise related to alternator wear

Installation Notes and Tips

Verify pulley groove count, plug clock position, rotation direction, and amperage rating before installation. Confirm the vehicle uses a serpentine belt drive and the correct Mitsubishi OE-style alternator configuration. Inspect the belt, tensioner, battery condition, and charging cables during replacement to help ensure proper system performance.

Quality Assurance

BBB Industries remanufactured electrical components are rebuilt to meet application-specific service requirements for charging-system replacement. Part number 11058 is intended for direct-fit service on the listed Subaru and Saab applications.
