this is what i have for a side view. I cut two wholes where the grills were. Originally there was only fiberglass behind some chicken wire. Anyhow, the person who makes this says it is okay to use the bumper in hot areas and it impedes the airflow to the radiator in a low %. The guy uses this bumper in Phoenix.
However, I cut those grill areas and I assume it should not be as a big deal for the radiator, plus there's an aluminum type of scoop to meet up to the radiator on the 4th pic in this thread.
