That BMW didn't leave big enough inlets for the M3 to get enough air up to 8,400 RPM. In this particular instance it just sounds a bit odd to me.
As I said, I have no data to back this up. I'm also not claiming to be right, it's just a thought I have on the subject of more air in this engine. Just posted it up here to see if anyone else thought it's a little strange BMW would've missed this "simple" improvement on the car.
What you don't seem to see is that BMW didn't "miss" it. Even F430's can be made more efficient.
