My local BMW wrench told me that (and I forgot the name of the company) the same company that makes the BMW filter makes the Bosch and several others. He believes the two are basically the same on the inside. I'd go with the Bosch unless I wanted to go with an extended drain filter in which I would buy the Amsoil, which costs, at least at my dealer, $1 less than the BMW filter. The dealer has both.
