I don't recall, I tested this on an '87 Monte Carlo SS years ago. They had more open space under the hood.
The difference was enough to convince me to move my CAI that was pulling fresh air low behind the bumper, but would heat up significantly at stops due to its proximity to the ground. It would heat up enough that it took blocks to get the IAT temp to drop.
I relocated the CAI to the top and back of the engine by the cowl and fixed my problem.
On my SS (vf) chassis, I used a roto-fab CAI. I insulated the box adjacent to the engine and reduced the time it took to cool down the IAT. I used a relocated sensor kit from Vector MS. I had uncoated headers at the time. Had the headers coated locally and my IAT temps at a light never went over 10* ambient. So I know that the coatings work for temp reductions.
