BMC's are made in Italy and are OEM in Ferrari's and other vehicles. Their fitment and quality is a tad step up from K&N.
I've run the BMC on my M3 and a "Streamline" filter made by Helene Performance which is similar to the K&N, and the BMC was better in my opinion. The fitment was superb.

but they were like $90 a piece for the M112.
