Sorry holmes...none of those links worked...

For the water sprayer your best bet is google, i dont have the best set up out there, just riged one up using the tube line from the back window and ordering a fine mist nozzle. VERY IMPORTANT, the water sprayer set up cost me like 20 bucks

However most diy will say you need a resoirvoir/pump. I just use our back window cleaner resovour. I live in NY so in the winter i like to use the back sprayer, so i put a T on the line so i can switch it to/from intercooler and back window, just make sure you run water through it only when your spraying on intercooler. I see my temps drop 15 degrees on my scanguage

I get a lot of questions about this, Here is a generic answer that will cover everything:
Here is what i used for the intercooloer diverter:

Here is what i used to divert the air and seal everything up, like "blimeycabrios

I have almost the same setup as cartar452, basically i spray mist of water then shoot it with co2, and yes co2 comes out of the hood scoop looking sweet
