its a way of super cooling your intake charge for denser o2 content and more power, usually sprayed on the inner cooler or into a heat exchanger plumed into your hot pipe to increase its efficiency, if done correctly you can yield well over 100% efficiency from your inner cooler (avg is 1% hp gain for a 10* drop in intake temp). the usual method is using a compressed gas such as n2o or co2 as the catalyst (both yield about the same cooling effect), the BAD if done wrong your motor can ingest the co2 for a huge power kill or even worse ingest large quantity's of unregulated n2o and blow the motorand in some cases people have abused it and frozen over their IC fins actually hurting performance (only in high humidity) . individual test go back and forth on the pros and cons of it but the science is very sound, as for now unless you can construct a ducted IC shroud to keep the co2 or n2o out just leave it alone.and just FYI this is not new, guys have been manually spraying motors/inner coolers between rounds of drag racing for years but the new street racing craze has made trunk mounted systems in style
best case scenario would be about a 20-30hp gain (if done correctly)
