Denso 210-4309 Alternator
Denso 210-4309 Reman Alternator Overview
The Denso 210-4309 reman alternator is a 12-volt, 110-amp charging component built for Subaru Legacy and Subaru Outback applications. It is designed for vehicles with internal regulation and clockwise rotation, making it a direct-fit option for restoring charging performance on the listed models.
Denso reman alternators are rebuilt to OE-style standards with tested electrical components, validated bearings, and precise assembly checks. For Subaru Legacy and Subaru Outback owners looking for a remanufactured alternator that matches factory fitment requirements, this unit is built around the original Mitsubishi OE family design.
Key Features
- 12.0-volt alternator with 110 amp output
- Internal fan and internal regulator design
- Clockwise rotation
- Remanufactured to OE assembly benchmarks
- Built for sensitive vehicle electronics and charging demands
- First Time Fit design for proper mounting and alignment
Product Details
The Denso Reman Alternator line focuses on OE-level fit, electrical integrity, and dependable operation under heat and load. During remanufacturing, critical components are tested to high electrical standards, rotor slip rings are finished to reduce brush wear, and bearings are checked against OE requirements with premium lubricants. The result is a charging system component intended to restore stable voltage output and support modern electrical systems in Subaru Legacy and Subaru Outback vehicles.
This part cross-references BBB Industries 11409 and Remy 12996 for the same application. The Denso 210-4309 also aligns with Subaru OE references used on the listed fitments.
Used For These Charging Issues
- Battery warning light caused by alternator output loss
- Low charging voltage at idle or under electrical load
- Dim lights, weak accessories, or unstable electrical operation
- Noise or wear related to alternator bearing failure
- Charging system faults on Subaru Legacy and Subaru Outback models
Installation Notes and Tips
Verify the vehicle’s year, model, amperage rating, and rotation direction before installation. This alternator fits 2010-2011 Subaru Legacy, N/A; fits 2010-2011 Subaru Outback, N/A; and fits 2012 Subaru Legacy, N/A. Confirm belt alignment, pulley condition, and connector match before final assembly. Because the unit uses an internal regulator, no external regulator setup is required on the listed applications.
Quality Assurance
Denso reman alternators are processed through electrical testing and OE-based inspection steps to support reliable charging performance. The 210-4309 is built to meet First Time Fit standards for proper mounting and dependable service on the specified Subaru applications.
