poor mans CAI ...
I have nothing better to do, so I addeda small ice pack ( froazen ) inside my stock air box under the air filter, but not in the way of the air intake on the fender and went for a drive.
This is a old trick hot rodders use, adding a bag of ice on the intake manifold, So it should work..
Any way's I really did not notice any great increase's in mpg or performance and the clips on the hemi air box are a P in the A, But I thinking on a hot day, thier might be a increase in performnace and with a little more improvement, this could be a great idea !!!

RE: poor mans CAI ...
The "cold" air coming into a CAI is ambient temp, versus air that has been warmed by the engine. The colder the ambient temp that day, the more effective it will be. Sticking a bag of ice in the intake box doesn't work because of the lack of surface area. Think of turbocharger intercoolers - they have thousands of fins, hundreds and hundreds of square inches, to effectively cool the incoming air.
You're not going to get much with a hunk of ice in the intake. Heat transfer depends on the temperature difference between the two materials, the surface area contacting both fluids, and the heat transfer coefficient. In the case of intake air and ice...you have a favorable temp difference, but a poor heat transfer coefficient...so you have to make up for it with lots of area.
