OEX Alternator 12V 90A Denso Style DXA4167

The OEX Alternator 12V 90A Denso Style DXA4167 is a new unit for applications that use a Denso-style alternator with a 12V electrical system and 90A output. It is a single-leg alternator with a 7 groove pulley, 55mm pulley outside diameter, and a mount leg thickness of 58mm.

This unit is listed with pin code IR234 and a dynamically balanced rotor. Those details matter when comparing alternators that look similar but differ in regulator function, mount layout, or pulley arrangement. OEX also identifies this as part number DXA4167.

Because there can be more than one visually similar alternator in this style, the safest approach is to confirm the OE number before ordering. The note against this unit specifically calls out that two identical looking alternators may have different regulator functions, so matching by appearance alone is not enough.

Application and Buying Notes

When comparing this alternator to the unit already on the vehicle, use the part number DXA4167, the pin code IR234, and the physical details together. The alternator is 12V, rated at 90A, uses a 7 groove pulley, and has a 55mm pulley outside diameter, so those items need to line up with the existing setup.

This alternator is described as Denso style and suited to Denso units, but the note is important: there are two identical looking alternators with different regulator functions. That means the OE number or a confirmed application match should be checked before purchase, rather than relying on shape alone.

The mount layout also needs attention. This unit uses a single-leg alternator mount with a 58mm mount leg thickness, which is a useful check when replacing an existing alternator. If the mounting ear, pulley section, or connector code differs, the alternator may not be the correct match even if the housing looks close.

At 4.42kg, this is a substantial electrical component and should be handled carefully during installation. As with any alternator replacement, inspect the belt condition, belt alignment, and charging circuit connections at the same time so the new unit is installed into a sound system.

The listed warranty is 3 years for passenger use and 1 year for commercial use. Make sure that use category matches how the vehicle is operated, and keep the purchase details and part number on file in case the unit ever needs to be checked under warranty.

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 DXA4167 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.
