Heres some intakes made by different manufacture for a different vehicle..
some shielding is metal , some is composite/plastic for the ones who can't tell them apart...
But you can see they're shielding the hot air from the filter..

 

As I mentioned earlier, CGS's intake WILL come with a heat shield that mounts at the filter, primarily to keep direct engine heat from it. With the heat shield installed the filter will be pulling its air from the stock fenderwell location.

SoCalHHR's will also be offering a new product soon, custom designed for the CGS system. Our product will offer additional insulation for the entire tube assembly for those who want to maximize the benefits of pulling cooler air.

More on our product as it reaches the end of the development stage...

 

here you go

You can use header insulation wrap tape (to wrap the metal/plastic/composite portion that attracts heat)

Or you can use insulation shielding

Or you can use the shielding that I saw that fits around a universal air intake.
