Part number 11438 is a Mitsubishi-style alternator with a conventional pulley, internal regulator, and 130-amp output for stable battery charging and electrical system support. This part cross-references A3TJ1991B for the same application.

Compatible With select Nissan 370Z and INFINITI models, including 2010-2020 Nissan 370Z, 2010-2013 INFINITI G37, 2011-2013 INFINITI M37, 2014-2019 INFINITI Q70, and other listed applications in the fitment data. Verify the vehicle’s build date and equipment notes before ordering, especially for 2010-2014 INFINITI and Nissan applications with date-specific coverage.

Common Issues This Part Can Address

• Battery warning light caused by alternator output loss
• Low charging voltage during idle or driving
• Dim lights or electrical instability from weak charging performance
• Accessory or starting issues related to insufficient system voltage
• Noise or pulley-related charging system concerns on the original unit

Installation Notes and Tips

Confirm pulley groove count, plug clock position, rotation direction, and amperage rating before installation. This alternator uses a serpentine belt setup and a conventional pulley, so belt alignment and connector indexing should match the original unit. Because fitment includes date-specific and trim-specific applications, compare the OE part number and vehicle build date to the catalog listing before replacement.

Quality Assurance

BBB Industries remanufactured electrical parts are built for direct replacement use in the listed applications. Part number 11438 is specified with OE manufacturer reference Mitsubishi and is cataloged for the exact vehicle fitments shown above.
