It is basically another version of nitrous, though instead of going into your fuel it cools the air down in your Intake/Intercooler to extremely low temps. I have heard of it, but I think it might be dangerous, then again, a lot of people say nitrous is dangerous. I think it could crack some parts in your car, because the tempature's get so low. I've heard it becomes as low as 30 degrees Farenheit. Seems too low when your car is running at 100 degrees just under the hood, not counting the internals. It is an idea that I will have to see put to the test before I consider using it myself.
