Has anybody else heard of these they have a bulb that goes in the intake and co2 gets blasted through it. It cools down the intake air then you can route the line to blast the co2 to the radiator to cool it down! I wonder if they work or are they junk?
The link you gave is just to the intake adapter. Its another $370 for the tank and installation parts.
For forced induction its much better to use one of the systems which uses the A/C system to cool the intercooler fluid. Works really well -- brings the water temps down to about 45 degrees and you never have to buy bottles. I'm sure something similar could be rigged for a non-forced engine.
Frankly though it seems like a lot to spend for the gains.
