well im biased since i have a procharger, but vortech doesnt have an intercooler kit, they have an aftercooler which isnt nearly as effective unless your doing pure hard drag racing, the air-to-air intercooler is the way to go on a street driven vehicle i got some charts and numbers to prove horse power gains between air-to-air vs water there in my other car right now, only time water wins is if there is ice in the equation

 

they both will not dissapoint, i own a vortech and im very hapy with it
