I used this to cover and insulate the outside of the filter box of the ColdSport cold air intake system for my 2016 MX5 Miata. I found it very easy to work with and if you follow instructions, very easy to apply and have adhere to the outside of the box. Coupled with the Heatshield tape it resulted in a very professional appearance and function.

I can feel hot air coming from the vents of my Carbon Creation hood yet the carbon fiber feels like ambient air temp, so I would say it seems to be helping! It did want to come off in some areas so adhesive could maybe be better but instructions say to use superglue for any edges if needed.
