Normally just water. But in winter I add some windscreen washer fluid to prevent freezing. Also can be used to fill washer bottle if you run out, saves plod nicking you.

Normal water will react with the intercooler and cause white deposites (aluminium clorate??/cloride??)
Best way to stop this is use de-ionised water, stuff out of a dehumidifier is good for this

I'd imagine the white stuff is just limescale like you get on your kettle or kitchen sink. Cure it by using ionised or boiled water instead of straight tap water.

dont mean to sound dumb but what are these spray features for? i mean i know they are for cooling but why wud you need it? are they there for if you decided to give it some heavy track miles? i.e constant hammering?

They add a nice spray onto the intercooler which makes the air denser giving more power, it also reduces high inlet temps i believe.
Only the JDM STi's have the auto button, during winter though, you use virtually if no water, its only in summer when you notice it drop (dramatically in some cases, normal motorway driving!).
Ive gone though most of my 12ltr tank on a trip down south and back

Press button, causes water to cool the air in the intercooler making it denser that should speak for itself though if its a freezing cold day it sort of defeats the object

But in short mineral deposits (limescale most common) are the only likely outcome from using tap or mineral water, thou I've never seen any scaled up intercoolers?

as above.... onto the i/c. As people without a spray kit will testify to when is't wet outside. The cooler air is hugely benefical and you get an increased push from it. Love going out in the wet!!!!

Chloride ions in water won't attack aluminium - it has a thin protective oxide coating. For the i/c spray you should use deionised water. Tap water and bottled water contain salts that are left behind on the i/c when the water evaporates due to engine heat.
