that sprays before the front of the intercooler. If it is a contant flow item you would need to ask the intercooler sprayer manufacturer for exact bottle dimensions. If your good at algebra you can calculate the flow rate by the amount of water in the bottle, of course I stink at algebra so don't ask me. I am not sure of that gains but I would rather take the money and go with the upcoming NIXIT Aquamist Group buy, but that is just my opinion. I personally don't want a whole lot of extra line flowing through my engine, I like simplicity. But again, just my opinion on the aquamist GB.
