"intercooler" All it does is spray water mist into the intake tract, like a nitrous kit, which lowers intake temps a bit, but doesn't help oil temp, coolant temp or underhood temps any. My roommate runs a aquamist water injection system plumbed in on the IC inlet charge pipe on his Saab, and it makes a very minimal difference, (like the difference between running on a 75 degree day v. a 90 degree day) and means you can't use your winshield sprayers. The JRSC would be good with a real, honest to goodness air to air IC.
