I've seen intakes for carbed cars that do that. Its an Aluminum tube with a round filter on it that runs to the lower corner in front of a tire. About 6" up from the beginning there is a wider round area with a cap that comes off and you can pack it with dry ice or regular ice. It chills a foot long section of the intake tube and lowers the IAT. I've never seen anything for FI cars though. The one I saw went on a nova with a SBC in it.

I'll bet what you saw wasn't for the intake - it was for the gas line. There is an item called a Cool Can that gets plumbed into the fuel line. The theory is that the colder the gas is, the denser it is, and therefore more power potential. My uncles used to run them on their cars at the track back in the '60's.
As was already stated about installing Dry Ice in the intake tract - Dry Ice is going to release Carbon Dioxide, displacing the oxygen that your engine needs for combustion. It might work to reduce the incoming air charge, but your engine is actually going to be getting less "air" (oxygen), so performance is going to be deminished.
