Different manufactures, same concept-->spray the IC when it gets hot or is under load.
I'm looking into buying one or the other. Factory IC on STI seems more than adequate if you can improve its efficiency. Heat of evaporation or the specific heat of water is an amazingly efficient means of cooling: consider the effect of wearing wet clothes with a 10 mile a hour breeze. It would be "nippy". Try 50 mph.
OK, now my stump speach in praise of Specific Heat of Water solutions.
A FMIC is just not a necessary expense for a street car or maybe ever. Why spend $1500+, when a $1-200 solution (above) will do.
That said, if you'll depend on automated water spray for your IC, then why not explore the same type of water injection system to reduce knock and lower exhaust temperature (e.g. Aquamist water injection, see http://www.chargedperformance.com ). Same idea (i.e. specific heat of H2O) but now you spray the water inside of the IC. Save on gas$$, increase boost, lower exhaust heat that ruins your turbo, increase reliability, torque, and speed--what more do you want?
