From what I understand, U.S. now uses the Euro Air Box in their most recent model year M3's.

You can get an adapter, or just get a filter that's sized appropriately. Less parts, less things to go wrong.
To be perfectly fair - there's nothing mechanical in an adapter than can "fail".

US and Euro airboxes are one and the same as of 2010.
