I/C spray
Know this has probably been asked a few times but I'm not going to be silly with it, i've read a little, I know obviously is keeps the intercooler cool by spraying it, i've got the button located on the right of my steering wheel, and that there can be different modes for it, auto, manual and off, how do i know this is actually doing it's job and what benefits and disadvantages does it have?
Cheers in advance.

Easiest way to see if it's working is to get someone to watch through the scoop when you press the button in manual. It should spray for aporox 3 second burst.
In auto it will be activated by the ACT (Air charge temp) sensor and spray accordingly. To see if this is working, pull the pipe off the nozzle and tuck it under your wiper. Go for a spirited drive in "auto" mode and you will see it occasionally spray when the ACTs get high enough to require it.
Basically it works by spraying the cooling fins with water. Water increases the heat transfer through the intercooler core and allows the intercooler to expell the heat quicker.
Blow on the back of your hand, now wet your hand and blow again. You will feel how much cooler it is when wet due to the increased heat transfer.
Intercooler spray works the same way.

Ah thanks for information frayz, I understand it a lot better now mate,
And yeah i think i must have been reading on a jdm spec or just general forum.
Mine is a type UK. So no it won't have the auto feature, so i'll have to do it manually, i'm guessing overall it cools the intercooler down and makes the car run a bit neater.

Yes, if you're UK spec then you won't have the auto feature. That's JDM only. You will have to add the spray manually. Although to be honest without reading the ACTs it's hard to say how much difference it makes. I used to poke the button on hot days for the placebo effect. Lol.
Would be worth chucking a thermocouple in there just to watch one day though.

If its a UK model then I doubt you'll ever use it. Caning through the gears, flying down the road and then having to take your hand off the wheel to press the button...... Never going to happen is it.
Better off emptying it rather than lugging around 5kg of water for no reason

I'll have you know I used it for the first time on Monday! Admittedly it was purely to see if the pipes were blocked or not but still... you guys!

Alright well i had a lil try last night and it seems as if it's empty or disconnected, judging by frayz reaction don't think I'll bother using it as from the recommendations on here, may be worth just seeing if it is connected still lol

I don't use mine often, but I sometimes use it on hot days or if I've been sitting in traffic for a while as I move off to speed up cooling. Does it make a difference? Don't know, but it makes me feel better.

The marshalls at Santa Pod hate them cos people end up dumping water all over the burnout area.
I have even seen ice cubes put on top of Top mounts for a 1/4 mile run.
