It remains to be seen, however, whether and how much recessed zones at the leading edge actually affect the airflow and increase drag overall.
It was about 2 inches deep. I might leave it like that for now but if i have to do any daytime driving in any kind of heat i'll have to dump heat in the cabin! I need someone to make me an automatic grille block. ......now who could i get?.......
