OEX Alternator 12V 80A Denso Style DXA4160

The OEX Alternator DXA4160 is a new 12V, 80A unit built in Denso style for applications that match the listed mounting and pulley details. It is supplied as each unit and suits a twin leg alternator mount, with 41mm inside mounting legs and a 160mm mount centre-to-centre measurement.

Key mechanical details matter here because alternators are not one-size-fits-all. This unit has a 4 groove pulley with a 57mm outside diameter, an M10x1.25 / 11 pivot hole, and an M8x1.25 adjusting hole. Those dimensions need to line up with the vehicle’s brackets and belt setup before purchase.

OEX lists this alternator under part number DXA4160 and pin code IR115. It is a new unit, not remanufactured, and carries a 3yr passenger / 1yr commercial warranty, which gives you a clear reference point for checking the correct replacement against the original fitment requirements.

For buyers replacing a Denso-style alternator, the important checks are voltage, output, mount type, pulley configuration, and hole sizes. This listing is for a 12V, 80A alternator with the dimensions recorded below, so those values should be matched carefully against the existing unit or parts listing.

Application and Buying Notes

Before ordering, compare the part number DXA4160 and the Denso style application details against the unit already fitted to the vehicle. This alternator is 12V and rated at 80A, so the electrical specification should be matched as closely as the mounting arrangement and pulley profile.

The mechanical fit points are just as important as the electrical rating. Check the twin leg mount, 41mm inside mounting legs, 160mm mount centre-to-centre, M10x1.25 / 11 pivot hole, and M8x1.25 adjusting hole. If any of those dimensions differ from the existing alternator or bracket arrangement, the part may not be suitable without further verification.

The pulley also needs attention. This alternator uses a 57mm outside diameter pulley with a 4 groove section. Belt alignment and groove count must match the vehicle setup, otherwise the belt may not run correctly.

If you are replacing a worn or noisy alternator, confirm whether the vehicle uses the same Denso-style unit and compare the original part number, mount style, and pulley details before placing the order. The fact that this is a new unit gives you a fresh replacement, but the correct application still depends on matching the listed specifications.

The listed fitment information includes Toyota Yaris applications from 2005 through 2015. That is a useful guide, but you should still confirm the exact vehicle variant and the original alternator details before buying, because alternator fitment can vary within a model range.

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 DXA4160 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 DXA4160, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA YARIS, TOYOTA YARIS 2005, TOYOTA YARIS 2006, TOYOTA YARIS 2007. 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: Please confirm fitment by matching part number DXA4160, Denso style application details, mount type, pulley specification, and the vehicle’s original alternator dimensions before ordering.
