Making A Heat Shield For My Intake

I got bored today, school's been out for 4 days, so I decided to make a heat sheild for my ebay intake. I started off by taking measurements of where the heat sheild would go. After making a quick sketch, I cut it out from some cardboard. After trying to fit it, I noticed some hidden plastic pieces and stuff that prevented it from going into place. So I recut the cardboard pemplate and made it fit. It fit in perfectly, but only had 2 holes for screws, so I decided to make it a bit bigger ad use the radiator hole on the left side. I'm now working on an AutoCAD drawing. I'll take some more pics later, but this is what I have so far...







I still don't know what to make the sheild out of...any suggestions would be appreciated

Yes, aluminum will get hot. Any metal will absorb heat. You would either need to powder coat it or make it out of a plastic instead. Of course, if you look around, you can find different insulation materials. I think the industrial stuff would work good.

no tar it will melt
drive it around real hard and open the hood and touch the intake that will tell you how hot if you don't have a thermal temp gun

My parents took it for about 15 minutes. When they came back, I touched it and if you hold it for more than 5 seconds, it will burn you My friend's CAI on his mazda will give you frostbite because of how cold it is after hard driving
