I installed a Cryo 2 kit / halo on the brother LNF cobalt. It only really worked well at the track. We had it set on a timer to be on for 14 seconds, or a manual switch. It did lower intake temps by 10-15 degrees depending on how hot it was outside, but his 1/4 times never changed much at all. He sold the car before we ever got to do any real testing after his baby was born.

 

Like I said, it works for the track..... ANywhere else, its just intimidation. Purging at a car show, stop light, etc. It becomes a talking point, thats about all. and a deterrent to anyone who doesn't know the diff. between CO2 and NO2
