IMO it would be better to spray it in a very fine mist. You'd need a water supply to use, maybe the a/c drainage? :dunno: but that might not be enough volume to keep up. You could use a small 12v pump, which would rob almost no power.

As far as cooling goes, you could spray pressurized air through several small venturi into the air intake before the throttle body. Of course, it takes energy to pump with the kind of pressure you'd need, so the power benefit wouldn't be realised unless you could scavenge wasted power from elsewhere.
