OEX Alternator 12V 180A Bosch Style BXA074

The OEX Alternator 12V 180A Bosch Style, part number BXA074, is a new rotating electrical unit with a 12 volt output and 180 amp power rating. It is listed with an internal regulator, pad alternator mount, and a 6 groove pulley, making the key installation details easy to check before purchase.

This unit is specified for Bosch applications and carries a clockwise rotation. The mount leg thickness is 94 mm, the mount hole diameter is 9.5 mm, and the note lists an ear mount M6, so matching the physical mounting points matters just as much as matching the electrical rating.

OEX positions this alternator as an aftermarket replacement with ISO9001 certified factory production and a warranty of 3 years for passenger use or 1 year for commercial use. At 8 kg, it is a substantial component, so confirming the vehicle application and the existing alternator style before ordering is a sensible step.

Fitment guidance and application check

• Fitment data is broad and includes multiple makes and models, so the safest check is to match the part number BXA074 against the vehicle application.
• Listed application families include Audi A3 and Q5, BMW 3, BMW 5 and X5, Fiat 500 C and Punto, Land Rover Defender, Mercedes-Benz C-Class, CLK, E-Class, S-Class, SLK and Sprinter 5-T, Peugeot 306 and RCZ, Renault Megane and Scénic, Saab 900, Skoda Octavia, Skoda Superb and Skoda Yeti, and Volkswagen EOS and Golf.
• Sample application years shown include Audi A3 2012 to 2016, Audi Q5 2008 to 2012, BMW 3 2005 to 2007, BMW 5 2005 to 2007, BMW X5 2008 to 2010, Land Rover Defender 2006 to 2016, Mercedes-Benz C-Class 1996 to 1998 and 2007 to 2014, Peugeot 306 1995 to 1997, Renault Megane 2005 to 2009, Saab 900 1993 to 1998, Skoda Octavia 2009 to 2013, and Volkswagen Golf 2005 to 2010.
• Because alternators can vary by mounting style, pulley arrangement, regulator type and rotation, the existing unit should be checked against the 6 groove pulley, pad mount, CW rotation and 12V 180A specification before fitting.

Application and Buying Notes

When replacing an alternator, the most useful checks are the part number, mount style and pulley setup. This OEX unit is BXA074, 12V, 180A, with a pad mount, internal regulator and a 6 groove pulley, so those details need to line up with the vehicle’s existing alternator and wiring arrangement.

The supplied fitment coverage is wide, but alternator selection still comes down to the exact application on the vehicle. Even within the same model family, differences in engine, charging system or accessory drive layout can change the correct part, so confirm the application carefully before ordering.

Physical measurements are also important. The mount leg thickness is 94 mm, the mount hole diameter is 9.5 mm, and the note specifies an ear mount M6. Those dimensions help avoid surprises during installation, especially where the original unit has been changed previously.

This alternator is listed as a new unit and weighs 8 kg, which gives a reasonable indication of the component size and construction. The 3 year passenger and 1 year commercial warranty provides additional buying context, but it does not replace the need to confirm compatibility against the vehicle and the removed alternator.

If you are matching a Bosch style alternator, check the rotation direction as well as the pulley section. This unit is clockwise rotation with a 50 mm pulley outside diameter and 6 groove pulley section, so the drive belt and mounting arrangement should be verified before purchase.

For the most reliable result, compare the old alternator’s part details, connector arrangement and mounting points with the listed Bosch style specification and BXA074 part number. That approach helps reduce the chance of ordering a unit that is electrically close but physically incorrect.

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 BXA074 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.
