heat shield help!!

I have a short ram intake on my 00 gp gt. I want to protect it from heat from the engine compartment. Does anyone know where i can buy a good heat shield or if i should make my own. If i do make my own, what materials should i use. Just looking for someone to point me in the right direction

I think i have a solution to my problem. I am gonna use some roof flashing for my heat shield and cover it with a high temp heat mat. This should help but i will post my results.
