how to install?

Also - another thing to keep in mind when injecting water in front of the intercooler is that this can actually decrease the efficiency of the intercooler. By lowering the temperature of the incoming air with water the intercooler can't remove as much heat as it would normally.
IC efficiency = BI - AI / BI - outside
Where BI = before intercooler temp and AI = after intercooler temp.
I say let the IC do it's job and inject after. :-)
