I've been reading about temp difference between these two grills for a long time now. Obviously there must be a difference in airflow or Ford wouldn't have made the change in '06.
It's just hard for me to see how that small amount of metal mesh could make much of a difference in airflow.
If the front grill makes a noticeable difference, how about the rear radiator grill? Would removing the backside grill help? I understand some of Fords test cars had it removed. Anybody try it?
