I have a 2016 F48 and it requires an 11428570590 filter. The tops of the filters are quite clear, the 11428575211 is stamped "ONLY ... B46B ..." whereas the 11428570590 filter is stamped "ONLY ... B46A ...". And while I couldn't find it on the underhood stickers, there's an identifying plate on the passenger side of the engine block that identifies the engine in my X1 as a B46A.

So... there are BMWs with the "Mini" engine, and the different flavors of the B46 are used in different models within the same model year. The only way to be sure is to look for the plate on the engine itself. The filter designs are completely non-interchangeable.

And if anybody would like a great deal on a few 11428575211 filter kits, PM me... 'cause I've got 'em!
