OEX Alternator 12V 210A Denso Style DXA4070

The OEX Alternator DXA4070 is a new 12V alternator rated at 210 amps and built in a Denso style configuration. It is listed with an internal regulator, a 6 groove pulley, and a twin leg alternator mount, so the physical mounting points and drive setup need to match the vehicle application before purchase.

This unit has an inside mounting leg measurement of 76mm, a mount centre-to-centre measurement of 126mm, and a pivot hole diameter of M10x1.5 / 10. The adjusting hole diameter is 11, and the pulley outside diameter is 49mm. Those measurements are the key checks when comparing against the original alternator or a replacement unit already fitted to the vehicle.

OEX positions this alternator as a quality aftermarket option with ISO9001 certified manufacturing and a warranty of 3 years for passenger use or 1 year for commercial use. It is supplied as a new unit and is sold each, which makes it suitable for replacement work where the existing alternator specification is known and the fitment details have been verified.

Application and Buying Notes

Before ordering, compare the part number DXA4070 and the alternator style against the unit already fitted to the vehicle. The listed 12V, 210A specification, internal regulator, twin leg mount, and 6 groove pulley all need to align with the replacement unit for a proper match.

Mounting dimensions matter just as much as electrical output. This alternator has 76mm inside mounting legs, a 126mm mount centre-to-centre measurement, an 11mm adjusting hole, and an M10x1.5 / 10 pivot hole diameter. If any of those measurements differ from the original unit, the alternator may not install correctly even if the electrical rating looks similar.

The 49mm pulley outside diameter and 6 groove section should be checked against the belt system on the vehicle. If the belt track or pulley style differs, the unit may not be suitable without further verification. The Denso style reference is useful, but the final check should always be against the vehicle application and existing component.

For commercial use, note the warranty is listed as 1 year, while passenger use is listed as 3 years. The unit is supplied new and weighs 7.24kg, which may help with handling and comparison when cross-checking against a removed alternator or a parts catalogue listing.

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 DXA4070 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 DXA4070, 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 210 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 2, BMW 2 2013, BMW 2 2014, BMW 2 2015. 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 fitment using part number DXA4070, the Denso style application, and the measured mounting and pulley details before ordering. Do not rely on vehicle make alone; check the alternator mount, pulley section, regulator type, and the dimensions listed here against the existing unit.
