Default 04 STi Zero/Sports Splitter Sprayer Questions

I'm looking for some information on the Cool-Action IIs for 04-05 STis. We have the IC sprayer which currently allows us to use the sprayer while standing still, and it covers the IC pretty well. I'm interestd in the Zero/Sports piece becasue better cooling is always good, however i'm concerned with how the sprayer works with the Zero/sports part. I know there is a slot for the sprayer nozzle, but I'm conerned with the sprayer while stationary. I autocross and I usually spray down the IC while in the staging lines. I'm worried the Zero/sports splitter will block the sprayer from effectively spraying the IC.

Does anyone know if the Zero/Sports splitter blocks the sprayer?
Does anyone know how much of the IC the sprayer will hit with the Zero/sports splitter?
Does anyoen have one on thier car to test for me (put a piece of paper towl on the IC, close hood, Hit button, profit).

I will try it on Saturday. I think it only hits the front part due to the slats, but I could be wrong. I know it works better than factory, but you have to put the factory skirt on it.

Thanks. I really apreciate it. I have worries that trade-off for moving airflow and killed the effectiveness of the stock IC sprayer. Since I do more autocross than open track events I'd want a more effective sprayer. Let it spray for 10 seconds a few times in the staging lanes really helps the IC stay cooler.

I added a boost referenced auto sprayer to mine. Anytime the button is on and I see double digit boost pressure , it sprays. You might consider that.

That'd be advantagous. Link?

Still, the advantage to me is really sitting still. Only way to cool that IC down.

NEGATORY- moving air +water will always cool better than just water.

I just bought the JDM auto button and there is a how-to in the forums on wiring it up.

OK- I did the test. There is only one sprayer, so it did what I thought: got everywhere but the lower corners.

My point is spraying while standing still is better than not being able to spray at all unless moving. Off the line on a summer day the STi is heat soaked like a mother. While there may be a few degrees drop while moving with the zero sports splitter, I'll take the hit and keep the ability to cool the if while standing.

Thanks for the test. Does it cover most of the ic while spraying then? Still an effective area?

Because the sprayer is pretty low, and the splitting fins end just above the sprayer ( I am guessing they did that on purpose) the intercooler spray gets to most of the intercooler ( in a fan shaped spray). I am thinking that the splitter does not change the sprayer's effectiveness, it only moves the air to try and equalize it over the whole intercooler.

Cool (no pun intended), I think I'll go ahead and grab it then. I just wanted to make sure the sprayer still hit most of the IC while stationary.

Thanks a lot dude.
