WAI 11058N Alternator for Subaru and Saab

The WAI 11058N alternator is a 90-amp, 100% new charging unit built for vehicles that need stable electrical output for everyday driving and accessory loads. It uses an internal regulator, internal fan, and a clockwise rotation with a serpentine pulley setup for direct-fit service on select Subaru and Saab applications.

Key Features

• 90-amp amperage rating for dependable charging output
• 100% new construction, not remanufactured
• Internal regulator for integrated voltage control
• Internal fan design for compact alternator packaging
• Clockwise (right) rotation
• 5-groove pulley included for serpentine belt systems
• Mitsubishi family alternator design
• Decoupled or clutch pulley: No

Detailed Description

Built for charging-system service, the WAI 11058N alternator is engineered to supply the amperage needed by modern vehicle electrical systems. Its 12-volt design, internal regulator, and included pulley support straightforward replacement on applications that call for a Mitsubishi-family alternator with clockwise rotation and a 5-groove serpentine belt interface. This part cross-references BBB Industries 11058 for the same application.

Compatible With 2006-2010 Subaru Forester, 2004-2010 Subaru Impreza, and 2006 Saab 9-2X. The WAI 11058N is a direct-fit charging component for Subaru Forester and Subaru Impreza models in the listed years, as well as the Saab 9-2X application shown in the fitment data.

What It Helps Address

• Low battery charging caused by a worn alternator
• Dim lights or electrical instability during driving
• Battery warning light concerns related to charging output
• Accessory power issues from insufficient alternator amperage
• Noise or belt-drive concerns tied to a failing alternator pulley assembly

Installation Notes and Tips

Verify pulley groove count, belt type, rotation direction, and regulator style before installation. Confirm the vehicle uses a serpentine belt system and matches the Mitsubishi-family alternator configuration listed for the application. Check belt condition, battery health, and charging-system connections during replacement to help avoid repeat failures. Fits 2006-2010 Subaru Forester, 2004-2010 Subaru Impreza, and 2006 Saab 9-2X exactly as listed in the fitment data.

Quality Assurance

WAI states that this alternator is 100% new and built with proprietary components and processes to support long service life and consistent performance. Part number 11058N is manufactured for charging-system replacement on the specified Subaru and Saab applications.
