MPA Electrical 10253 Alternator

Remanufactured Alternator for Subaru Applications

The MPA Electrical 10253 is a remanufactured 12-volt alternator built for Subaru charging-system service. It delivers 140 amps and uses an internal regulator, internal fan, and a 6-groove serpentine decoupling pulley for the specified applications.

Compatible With Subaru WRX, Crosstrek, Impreza, and XV Crosstrek applications listed below, this alternator is a direct-fit charging component for vehicles that need stable electrical output and OE-style mounting and rotation characteristics.

Key Features

• 140 amp output for 12-volt charging systems
• Remanufactured MPA Electrical unit
• Mitsubishi manufacturer design
• Internal regulator for integrated voltage control
• Internal fan for alternator cooling
• 6-groove serpentine decoupling pulley
• Clockwise rotation
• Clock position: 11:30

Detailed Description

MPA Electrical part number 10253 is a remanufactured alternator engineered for Subaru charging-system replacement needs. It is specified with 140 amps, 12 volts, clockwise rotation, and an internal regulator, making it a practical replacement for vehicles that require consistent battery charging and electrical system support. The Mitsubishi-built design and serpentine decoupling pulley help match the original application requirements for the listed Subaru models.

This part cross-references Karlyn 11869 for the same application. The MPA Electrical 10253 also cross-references OE-style numbers 23700-AA910 and 23700-AA911 for the same fitment family.
