Here are 4 atached photos. I am trying to show the sides of the original holes that were 3 inches wide and then filled in with foam board to bring them to 1 and a half inch wide, then trying to show looking at the top that I put a piece of one inch filler foam in for the cold air intake. and covered it with HVAC tape. then there is a pic showing the aluminum pieces I used to finish it off. I did cover all of it in HVAC tape. The hole you have may be to thick for the rvairflow. So i just shored out the hole for a good fit and smooth air flow.
