Default heat shield for IC

I've noticed that my IC intake pipe gets really hot from being right behind the radiator, anyone have a heatshield pic or idea on how to keep it cooler?

If you're talking about the pipe from the turbo to the IC, the radiator has nothing to do with it. It's hot because the air inside it is hot as hell, thus the need for the intercooler.

After a 20 minute session, the coldside IC piping is warm, but not any warmer than the rest of the engine bay. The hotside IC pipe is scalding hot.

the best you can do it use a material that sheds heat, like aluminum. and on the cold side, use something that retains it, like silicone.

i took 5-8*F off my iats at cruise by wrapping my charge pipe (that goes behind my radiator from my ic to my throttle body) with 2 layers of exhaust header wrap. the pipe is ebay 3" aluminum ic piping.

tested on a 98-100*F day freeway cruising
i used megasquirt to check my iats, wrapped pipe, drove again.
outside temp monitored with an after market outside temp sensor installed in front bumper.

Sorry, I was talking about the pipe leading to the tb. On mine it's vertical from the swaybar to the throttlebody, about 6in behind the radiator. I have removed the a/c and thus the a/c fan shroud as well.

After a drive, that pipe felt almost as hot as the pipe leaving the compressor, but the pipe coming off the cool side of the IC is cool to the touch.

I feel like I'm re-heating the air after it was just cooled.

How long after the drive did you feel it? If it was more than 2 minutes since the car was shut off, it could have heat soaked and gotten hot. What do your iat temps look like when you're driving?
