I agree with this way of thinking. I think that my top grille block will be a year-round thing. The bottom one will be the one that gets adjusted. Plus, if I remember correctly, my A/C condensor coil is in front of the lower opening, and I do want for it to function very well.

On a separate note, I also want to try to find a way to get some air flow over the battery, since I think that the heat of the engine compartment is the reason they have such short life expectancies down here.
