How does air from your cooling fan or ram air set up get into the engine without first going through your mass air meter?
If you have a cone type filter in your engine compartment that is not shrouded from the cooling fan, you can experience some fan wash problems effecting the air entering the engine. But, even in this case the air still goes through the meter first, it just may not be the same amount if it was properly shrouded.
