First, thanks for bringing the charcoal filters to our attention. I'm surprised no one had mentioned them previously with the various Gruppe M air box installations. There is now another wrinkle in the airbox saga. I've found a snorkle installed in the airbox, I assume in the open hole others have. No aluminum block off plate, but the snorkle in this picture. My M5 build date was November 2012. Oh, and the torx on my airbox are T25, not T20 if somehow there has been a slight redesign of the box....?
