I'm looking into a stainless steel heat shield mainly for appearence, but any cooler temperature never hurts. I want to purchase one, as long as I know it won't actually increase the temperature. I'm thinking stainles steel will get pretty hot, in which case it won't do any good. My question is, will the SS shield heat up to actually DECREASE the preformance? If not, I'll buy.

I also found an aluminum shield--any suggestions?

 

Those things are a waste of money. If you are looking to create a functional heat shield or barrier between your cone filter and the hot air from the engine bay. I would say that you would be better off buying an 18" x 26" (16 gauge) aluminum baking sheet and making a box yourself. $25.

Here is a pic of the one I made for my 5th gen a few years back.



Small sheet of 18 gauge mild steel ($20) and a strip of weather seal from the J/Y (free) and some left over vacuum hose to keep the CAI tube from rubbing up against the steel. Took me about 30min to create a template using cardboard and a pair of scissors.

 

you could also do the same thing Ghost suggested with hi density plastic. I see you live in so cal you could give s & w plastics a call and get your material from them- Riverside,Ca (951) 781-4950.
they might have a location closer to you.

From my experience there is less heat transfer when you use plastic, just look at what auto manufactures are using or look in tech magazines for intake shoot-outs and see what brands/materials are coming out on top.

The plastic will be easier to manipulate as well. And whatever you do don't waste your money on that item you posted, if your looking for hp gains, the stock intake will probably perform better!
