OEX Alternator 12V 130A Mitsubishi Style MXA2066

The OEX Alternator MXA2066 is a new 12V unit rated at 130A, supplied in a Mitsubishi style configuration with a twin leg alternator mount. It is listed with an internal regulator, a 6 groove pulley, and a pulley outside diameter of 58mm, so it suits applications where those physical and electrical details match exactly.

This alternator is identified with part number MXA2066 and pin code IR50. The mounting details supplied are an 79mm inside mounting leg measurement, 152mm mount centre to centre, an M8x1.25 / 8.5 pivot hole diameter, and a 9mm adjusting hole diameter. Those dimensions are the key checks when confirming replacement fitment.

OEX positions this alternator range as an aftermarket option built around quality and reliability, with ISO9001 certified factories and a warranty of 3yr Passenger / 1yr Commercial. The unit weight is 5.68kg, which is useful to note when comparing against the removed alternator or checking postage and handling requirements.

Application and Buying Notes

This alternator should be checked carefully against the original unit before fitment, particularly the 79mm inside mounting legs, 152mm mount centre to centre, and the M8x1.25 / 8.5 pivot hole diameter. With a 12V system and 130A output, it is important to match the electrical specification as well as the physical mount, especially where the vehicle uses a twin leg alternator arrangement.

The 6 groove pulley and 58mm pulley outside diameter are practical identifiers that help distinguish this unit from similar-looking alternators. If the pulley section or diameter differs from the removed part, do not assume interchangeability. The internal regulator also needs to match the vehicle’s charging system setup, as regulator type is a critical compatibility point.

For buyers comparing options, the listed 5.68kg weight, IR50 pin code, and MXA2066 part number offer useful reference points when verifying an existing alternator, matching photographs, or comparing supplier listings. Where the application is being checked from a vehicle register, use the exact model details only as supporting information and always confirm the physical measurements first.

The warranty period is listed as 3yr Passenger / 1yr Commercial, which may matter if the vehicle is used privately or in a commercial setting. As with any rotating electrical part, correct fitment is essential before installation, and the alternator should be matched to the vehicle’s mounting points, pulley configuration, and regulator arrangement rather than by appearance alone.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number MXA2066 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number MXA2066, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SUBARU BRZ, SUBARU BRZ 2012, SUBARU BRZ 2013, SUBARU BRZ 2014, TOYOTA 86, TOYOTA 86 2012. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm compatibility using the MXA2066 part number, IR50 pin code, 12V/130A rating, twin leg mount details, and the supplied pulley and hole measurements before ordering.
