That white ring is like a felt seal.
O-ring is for the housing.

Looks the same as the Alloytec filters.
They have a 26mm socket on the cap and done up to 23Nm

Probably from the same German factory.
These are 25Nm and a 36 socket.

Who knows why they chose such a large size for a comparatively low torque.
I bet no-one sells a 3/8dr 36mm. And space does not allow a 1/2-3/8 adaptor to use 3/8 torque wrench, so you must use 1/2" torque wrench on one of it's lowest possible settings. Not cool Bavarian's!

I'll have to check and see what filter I have in the garage for the BMW but yes, I think it's a 36mm hex. Probably went oversize because the housing is high density plastic and the larger hex would be stronger and more resistant to damage than a smaller one. Having said that, the one on the boys car has been butchered

Just had a look, the 330i uses a 2592P filter that looks to be bigger.

Still, it makes sense to use the same 36mm hex fitting standardized across the BMW range, makes it easy for the service guys.

Cast metal on the mini.
