My thinking on leaving the center open was to maximize airflow to the radiator through the smallest opening possible. I could cover the middle (around the license plate holder) of the center and leave the sides, near the foglight openings clear. But it seems to me, that would reduce the cooling efficiency since the airflow would not have as direct route to the radiator. Am I looking at this wrong?

The center opening is the only one that goes directly to the radiator. Also, the passenger side opening (where a foglight would be in some models) actually goes to nothing. The drivers side opening appears to go to the AC, but since I don't usually run the AC, this shouldn't be an issue.
