If you mean the stock ic sprayer I would not recomend it due to its high corrositivity. Now with a high presure pump sprayed into the intake tract using the tank as a resevour, yes but I recomend using a controller from one of the many kits available.

how about just mixing in a small amount of methanol/ rubbin alcohol with mainly Distilled Water. I heard this will help lower the freezing temp a bit in case it gets cold at night?

^^^This would work, but if it is cold enough to freeze then you shouldn't need to worry about spraying the intercooler. I do not know if the pump/seals in the OEM pump are made to handle alcohol in the reservoir though, so it may be a better idea to just let it freeze.

I take it you are trying to get more cooling on the intercooler. I wouldn't recommend doing so. Methanol is flammable and you really don't want to spill that stuff on yourself when filling the bottle. Granted it may take a while, but you could eventually have eyesight problems from the methanol being absorbed through your skin if it happens again and again. I would stay away from spraying flammable solvents on your intercooler.
