So I'm am finally about to do this along with my GT350 manifold install. I got hit with ye ol' covid in the fall when I was going to install it and then it got too cold to install it and my garage barely fits my car in it so I had no room to do it. While everything is out of the car, I installed the heatshield Products I-M shield on the underside of the intake manifold and their heatshield mat on the airbox. I got the 24" x 48" roll and it was way too much. Could probably do 2 or 3 airboxes with that amount. The material cuts very nicely with a decent pair of scissors and cuts ok with a razor blade.
**WARNING** If you are going to do this, do it outside and wear gloves and long sleeves. It is essentially sticky fiberglass with a reflective coating and the fiberglass gets EVERYWHERE when you cut it and makes you extremely itchy. Ask me how I know lol.
I started buy making a cardboard template of the airbox lid and leaving a little extra room to account for the dips in the lid and have extra for trimming
I cut it out, peeled off the sticky backing, and lightly put it in place. I then used a wooden roller to have it attach firmly.
I used another piece of cardboard and traced the opening in the lid for the intake tube and cut it out with a decent amount going up towards the top of the lid. Took a bit of trimming to get the curve just right but it was worth it. I applied it and trimmed it to fit on the box.
Now came the fun part. Doing the airbox tray. The GT500 airbox is pretty much a shrunk down a bit laser scanned copy of the space it occupies with a lot of complex shapes. To tackle that, I laid out some masking tape and traced the spot with a sharpie. Peeled it off, cut it out and slapped it on the heatshield material. Make sure you put it on the shiny side as if you put it on the back side it will come out reversed. I'd leave about 1/8" around what you trace to give it room to conform to the curves.
I continued this around the airbox until I had all the major areas covered. I also used some scraps to fill in smaller areas. The material conforms to curves quite well and having the roller really helped to get it stuck down. I only had to do probably 10 small relief cuts for tightly curved spots.
I then went over all the spots between the big panels and the sides of the lid with a roll of the heatshield material that was more lie a roll of tape. I got the 1 1/2" by 20 ft roll and have way too much left over.
I still have to attach the snorkel and wrap that and I wat to test fit it again and see how much room there is on the side where it sits against the inner fender. There are a lot of indents for clearance on that side and I want to make sure the fiberglass material doesn't interfere with it fitting, plus I don't think that side will see much heat. But if there is room I will apply it on that side as well as I have so much left over.
All in all it took me about 3 hrs to do but I was trying to figure out how to tackle it and I started off being very meticulous, but by the end I was just slapping scraps on and trimming them to fit while on the airbox.
Here is what I used if anyone is interested in doing this.
