Hi,
I blocked the upper one because it is flush (the lower one is recessed) and it helps the air flow up over the hood. Also, the standard upper grill is more closed than mine is, so I felt more confident going without the cooling air. And there is the slot just above the bumper, too.
It worked perfectly well today in very slow/stopped traffic on Route 128 with the temps in the upper 90's.
