I have always wondered about this: in the lower air dam, on the passenger side, is a cutout, and behind it is an air intake, which travels straight back and outlets its cool air intake right on to the pass. side motor mount, which is located under the exhaust manifold. My question is, why?

By the way, I have installed a K & N air filter in place of the dirty MB one, and have noticed that the air is intaken behind the pass headlight housing. Can I route that intake which goes to the MM into the filter box?
