Best HeatShield material

[drifter420]

What material that is readily available @ home Depot or the likes will withstand heat and prevent heat transfer the best? ( minus some form of heat wrapping.. that will be added anyways, just the material itself I"m inquiring bout )

I've seen a lot of people use plexi-glass but I think they chose that material cause it's clear and for show

Just fabricate aluminum and insulate with this

Thermo Tec has all sorts of sound/heat insulation. You can order it online at www.driverfx.ca [type "thermo tec" into the search box, you'll get 3 pages of results] or special order it through Canadian Tire.

So the material doesn't matter.. only the insulation for heat control? So any material will suffice?

Well I wouldn't use wood....I used aluminum because it was easy to cut and form/drill and mount....then insulated it....moved my IAT over behind it also...really made a difference....On both the Dodge R/T and the GTO...

How much heat are we talking about? For underhood temps I'd probably choose a sheet of aluminum, because it's easy to form and cut. That would be good for a filter airbox, for example. Either polished aluminum or silver paint will do lots for keeping heat transfer down.

OK.. here's the thing. I want to keep the stock airbox appearance.. so I"m guttin the internals of it. WAS going to get intense intake tubing but being close to $30CAD per foot after shippin to Canada lookin for other route. On one side of the airbox is a nice hole that isn't gettin used. So I wanted to cut/bend/extend that side of the airbox to utilize it, so wondering what material to use to extend the side of the airbox.

I want to put some kind of heatshield material on the inside of the airbox vs. the outside. Get an AEM dryflow filter.. and find some nice black tubing thats smoother then the accordian tube that the stock engine comes with between airbox and TB.

Basically I want to make it look as stock as possible, and as cheap as possible ( For legal reasons that I don't want to go into and it would be another thread all on its own.. lmao )

P.S. I was told that I could use the windshield visor reflective thing you see some people drape over their front windshield and put it inside the airbox for the heatshield.. it's a lot cheaper, but I wonder if it would start a fire in there?

The ghetto cold air intake material of choice appears to be the PVC pipe from Home Depot....3"-4"....some of them look very good....
IMHO if you put the heat reflecting material inside the airbox you just manufactured a oven....it needs to go on the outside to reflect the heat....if it is inside there is nowhere to reflect it to so you end up with a convection situation....the window reflector reflects sunlight and UV....I do not know about heat....your talking radiant heat here...
If I were you.....I would consider utilizing a heat reflective tape....cheap and very effective....Home Depot sells it back by the insulation... http://www.adlinsulflex.com/heat-resistant-tapes/fiberflect-tape/
you can wrap your airbox and the will have no impact on any warranty or inspection criteria that I am aware of....of course i don't know much about Canadian "rules"....2nd you could drill holes in your airbox out of the line of sight....fabricate a Cold Air Intake (with the pvc) and route cold air up to the new inlets to your stock airbox...this should be able to be done in a stealth mode.....

Good point bout turnin it into an oven.

Well.. As long as the officer doesn't want to be a jerk, it's alright.

I had a few people that has been pulled over and was given ticket for having a CAI even though it passed emission, and went through court. Basically the officers says that you're altering the emission system even though you pass emission testing.. ***?!?!?!

I'd seriously consider overthrowing the goverment if they did that here

I use self stick aluminum pipe insulation on my upper intake pipe. It comes in rolls about 3 inches wide.
