OEX Alternator 12V 90A Bosch Style BXA4015

The OEX Alternator 12V 90A Bosch Style is a new rotating electrical unit with internal regulation, a 6 groove pulley, and a 90 amp power rating. It is listed under part number BXA4015 and suits Bosch applications, so matching the part number and mounting details is the most reliable way to confirm the correct replacement.

Key physical details include a single leg alternator mount, 156mm mount centre to centre, 56mm mount leg thickness, 10mm pivot hole diameter, 10mm adjusting hole diameter, and a 17 shaft dimension. The pulley outside diameter is 56mm, which matters when checking belt alignment and replacement against the original unit.

This alternator weighs 6.4kg and operates on 12 volts. For buyers comparing units on the bench or before removing the old alternator, those dimensions and the Bosch style configuration are the main checkpoints alongside the part number BXA4015.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factories supporting engineering, testing, and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, compare the part number BXA4015 with the unit already fitted to the vehicle, then check the Bosch style designation, 12V system voltage, and 90A output. Matching the mounting pattern is just as important: this alternator uses a single leg mount, 156mm centre to centre, with 10mm pivot and adjusting holes.

The pulley arrangement should also be checked carefully. This unit has a 56mm outside diameter pulley with a 6 groove section, so the belt type and pulley alignment need to suit the existing setup. If the belt system or bracket layout differs, the part may not be a direct match even if the vehicle model appears on a fitment list.

For buyers replacing an older alternator, the 17 shaft dimension and 6.4kg weight can help when comparing the physical unit on the bench. These details are useful when confirming that the replacement is the same style and size as the original Bosch application.

Warranty terms are listed as 3 years for passenger use and 1 year for commercial use. That is useful buying context, but it does not replace fitment confirmation. The safest approach is to verify the old alternator’s tag, mounting points, pulley specification, and electrical rating before finalising the order.

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 BXA4015 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.

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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI 80, AUDI A3, AUDI A3 2000, AUDI A3 2001, BMW 3, BMW 3 2001. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching part number BXA4015 and checking the Bosch style application, 12V rating, 90A output, single leg mount, 156mm mount centre to centre, 10mm holes, and 6 groove pulley before purchase.
