For the selected E92 325i offer, core only means the oil-to-coolant heat exchanger. It does not include the oil-filter housing, filter or cap. Establish that boundary before deciding whether the package covers a diagnosed repair.
The cooler mounts on the filter housing. A problem somewhere in that assembly does not, by itself, establish which component or seal requires replacement.
Keep the Australian N52 application precise
The selected E92 N52 cooler core uses reference 11427525333. Its listed scope is the Australian E92 325i coupe, 2.5L N52 petrol, 150kW, built 03/2010–10/2013.
A 325i badge or N52 description alone should not extend that scope to another build, body or engine specification. Confirm VIN, actual build month and the original cooler reference.
Compare the curved outlet and housing interface

Match the core shape, curved outlet orientation, flange and fluid-port arrangement with the original unit. Use a complete view to establish which side is being compared, then a clear view of the housing interface.
The sealing face matters as well as the visible upper shape. If the interface or a port is obscured, obtain the missing view rather than inferring it from a similar BMW cooler. The photograph is not a source for unlisted measurements or tightening values.
Plan the housing and seals separately
The selected package is one engine-oil cooler core. Have the installer confirm the required replacement seals before fitting and inspect the associated housing as part of the diagnosed repair. Do not assume that a core-only package resolves damage to a separately retained component.
This engine-oil cooler does not replace a transmission-oil cooler. Keep the fluid system and component identity clear when sending photographs or asking for a quote.
Prepare a useful core-only enquiry
Send the VIN, build month, engine specification, original reference and accessible photographs of the whole core, curved outlet and mounting face. State whether the enquiry concerns the core, housing or both, and have the installer identify the required seals and surrounding parts. That gives the parts comparison a defined scope without turning a package description into a diagnosis.
