The only issue with that is...aesthetics. I'm no designer, but I've a bitch of a time trying to figure out a way to elegantly add a scoop. I think the most acceptable addition would be a NACA duct, aiming in. And for symetery's sake, a reverse NACA could be added to the other (faux) side as a draw-out/vent of engine heat/air.

Will I do that?...the magic 8ball says no. But I think that would work.

I think we've now discussed this to death. The only thing left is for someone to produce some actual figures of the air intake in "real world" driving conditions. I'm afraid I can't do that due to lack of access to one of your M3s. Out of interest what do they cost in the USA and what is the present price of your fuel?
