I'd be interested in the internal structure of the two filters. The external appearance could be deceptive. They could be similar or very different in filtering ability.
Do you have any recollection of the original factory filter versus the filter put on at the 1000 mile service? It makes you wonder if we are paying for extra protection on a high performance car or just a price gouge for a prestigious name. By the way, Mike, haven't I seen you post on Dentaltown?
