i'd be careful about it, cause it could mess up your engine really bad, cause CO2 is used to stop fires (used in fire extinguishers). make sure you just use it to cool off the area around your intake or intercooler and not inject it into your engine itself.

 

Ok guys heres the deal, I have bought this system and if you are looking at buying one remember a few things, make sure you get the 3" pipe and not the 2.5", and um it is not cheaper then NOS. I have had it for a few months and another thing is you might as well get atleast a 10lb bottle cause this stuff runs out fast especially if you have the purge kit also which is what i have. It still costs about 23 bucks to fill up a 5lb bottle and if you ask me it really isn't worth it. I have found that it makes a nice show peace but on a NA lancer which is what I have it only produced about a max of 5 hp (just a guess) which is way less then NOS but it is perfectly harmless to your motor. All it does is it travels through a tube that you insert into your intake pipe and comes out the other end and drops your intake temp about 50 degrees, it does not purge into your motor. Oh by the way when the bottle gets fiiled up it will get really cold not hot like the other guy said. Anymore questions just let me know, and by the way the do have a fuel line cooler and a itnercooler sprayer available.
