OEX Alternator 12V 180A Denso Style DXA4133

The OEX Alternator DXA4133 is a new 12V, 180A unit built in a Denso style for vehicles that use a Denso alternator layout. It suits unit make Denso, uses an internal regulator, and is supplied as a twin leg alternator mount with a 6 groove pulley.

Key mounting details are listed at 75mm inside mounting legs with a 10.5mm adjusting hole diameter and an M10x1.5/10 pivot hole diameter. Those measurements are the important checks when matching an alternator, because alternator fitment depends on the mount pattern, pulley setup, and electrical configuration as much as the headline amperage.

This is a new alternator, not a remanufactured unit, and it carries a 3 year passenger / 1 year commercial warranty. The unit weighs 7.1kg and is identified by Part No. DXA4133, with pin code IR169 and OEX brand identification for ordering and comparison.

For buyers comparing replacements, the main points to verify are the 12V system, 180A output, Denso-style construction, 6 groove pulley, internal regulator, and the twin leg mounting arrangement. Matching those details closely helps narrow the replacement to the correct application before ordering.

Application and Buying Notes

Alternators need to be matched carefully, especially where the vehicle uses a Denso-style unit with a twin leg mount. On this part, the useful checks are the 12V system, 180A output, 75mm inside mounting legs, M10x1.5/10 pivot hole diameter, 10.5mm adjusting hole diameter, and 6 groove pulley with a 50mm outside diameter.

If you are replacing an existing alternator, compare the part number DXA4133 and the pin code IR169 with the unit already fitted to the vehicle. Those identifiers are often the fastest way to confirm you are looking at the same alternator family before moving on to the mounting measurements.

The 180A output is the headline electrical rating, but fitment still depends on the physical layout and regulator style. This unit uses an internal regulator, so the vehicle’s charging system arrangement needs to suit that design. If the old alternator differs in mount spacing, pulley groove count, or regulator type, it should not be treated as a direct match without checking further.

Because fitment can vary within a model range, it is best to confirm the application against the vehicle’s existing alternator and mounting points, not just the badge on the car. The BMW 2 fitment references listed here should still be checked against the exact vehicle and the installed unit before ordering.

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 DXA4133 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA4133, Brand OEX, Description OEX Alternator 12V 180A Denso Style, Adjusting Hole Diameter 10.5, Pin Code IR169, Power Rating (Amp) 180, Pulley Section 6 Groove, Suits Unit Make Denso, Alternator Mount Twin Leg.

OEX Alternator 12V 180A Denso Style. Part number DXA4133 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4133, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 2, BMW 2 2014, BMW 2 2015, BMW 2 2016. 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 fitment by matching Part No. DXA4133, pin code IR169, the Denso-style twin leg mount, 12V system, 180A rating, and the 6 groove pulley against the vehicle’s existing alternator and mounting details before purchase.
