Hubbly, why did you mount the nozzles on top of the intercooler between the radiator?

Could you not fit them somewhere on the bumper and have them spray directly at the intercooler?
 
I did this on my Megane 225, I used the headlight washers to spray on the IC

Here is a few pics of the washers mounted upside down on the inside of the bumper




 
We have used similar set-ups on Impreza's for years.
We have also taken it a step further in the past for 1/4 mile........ C02 fire extinguisher feeding a metal spray bar ;)
