Default Newbie STI question

Just picked up an '04 STI. This may sound silly but, do you guys use regular tap water in your intercooler sprayers? Distilled water better? Thanks!

Not a silly question at all. Distilled water is best to use so there is less chance of any build up or anything else bad.

I use the super secret special magic water (add Ice Cubes on race day)
Regular 'ol tap water should work just fine.

should also use distilled in radiator too. Impurities like sulfur etc can clog up you IC sprayer & even radiator.

Most water out of the tap has alot of chemicals in it example Chlorine etc.

Distilled is boiled & filtered thus pure water no impurities

distilled water will also evaporate more readilly, but its probably not enough to make a difference.

if you want to use alcohol, its probably a bad idea to go pure alcohol, but like 50/50 or less mixed with distilled water should give you lower temps than water.

If you don't want to burn out the pump stop mashing the button when half of the planet is frozen.

Distilled water. No Alcohol, widshield washer fluid, water wetter or anything else that has been speculated upon. Just plain, boring distilled water.

For the winter leave it half empty (or full depending upon your view). Although I will admit in the spring it's a bit scary to hear a very loud clunk from the rear until you realize it's just the giant ice cube in there.

The big difference between using bottled water and distilled water is, the bottled water still contains minerals that will be left behind on your IC once the water evaporates. (minerals are supposed to be in drinking water, but you don't want them on your IC)

Use distilled water. Maybe with a little splash of rubbing alcohol to prevent freezing in the winter/algae growing in the summer. But not so much alcohol as to pose a fire hazard...whatever doesn't evaporate on the intercooler is going to drip down onto a hot engine.

Don't laugh, but I'm a really new noob here: What about those of use who live in wet climates--doesn't the IC get wet from rain water entering the engine bay? What makes the impurities in tap water worse than what comes from the environment?

I'm sure it does get wet during rain - just gotta drive about 115

As for the alcohol - I doubt that the stock pump and lines are capable of dealing with alcohol. Those lines don't look too durable.
