Basically a nitrous system that is triggered off a microswitch at WOT and a elongated oval pipe (i guess with small holes in) which looks to be mounted on top of the I/C and hey presto ice cold nitrous (or CO2) spayed over the I/C whenever the loud peddle pressed! Personally I would put a manual button in aswell for those heat soak moments before the run but a good idea none the less!
And the whole lot for about £321 I think which is not to bad given the potential.

From: The quietest Cobb stage 2 in the world
I used this pressure switch for a WOT setup along with a manual switch in the cabin. It is adjustable to 4psi to 15psi. (1bar=14.7psi) The factory windshield washer pumps are always hot and the factory windshield washer switches just connects the pumps to ground. So I tapped the always hot wire of the washer pump connecting it to a seperate I/C sprayer pump. From the I/C pump one wire goes to the manual switch. The switch is connected to ground. The second wire off the I/C sprayer pump goes to the pressure switch. Again the switch connects to ground. During the winter I just pull the ground wire of the pressure switch to disable it. http://img.villagephotos.com/p/2003-...6/EBAY2051.jpg
I mounted the I/C water pump below the gas filter, it's out of sight, and inline with the water hose for the front windshield. All that looks abnormal is a pressure switch mounted on the strut tower. You just have to tap one wire, it's already fused, and if you use a manual switch also-you just have to pull only one wire into the cabin. Pressure is tee into BOV line and I have it set close to when the ECU goes to open loop monitoring. I have several of these switches, but I don't know if it would be worth shipping them overseas.
