Just a thought for further development, but has anyone thought of installing a pair of windshield washer nozzles inside the lower front fascia that point inward and down toward the intercooler?
Using an aftermarket windshield washer pump and a reservoir with Distilled Water, this may be a way to keep the intercooler working more efficiently. If the idea works, it could be tied to WOT or boost level or a check valve that triggers a switch when vacuum turns to boost or (your idea here)....
Distilled Water would be key, as sulphur content (and probably other mineral/chemical content) is death to aluminum cooling fins. Ask anyone who services HVAC units around a source of Sulphur water....
