Easy mount no drilling $10.00 in parts, I used an aluminum L bracket. It can be removed easy-15 seconds. We have cops and roadblocks around here and it was a matter of time. It sits 3" from the heat exchanger with airflow on all four sides of the plate. I don't think airflow will be a problem unless the car is driven very hard. It doesn't get too hot around here either. I'll test it.
