Used Aqua mist for about 15 months now and its the business good if u are sitting in traffic and the charge air temp goes above 55/60 Deg and u are running big boost risk of detination. The spray will cool it down till the intercooler is doing its job again. I had it on a pressure switch so when it reached just short of full boost it was activated, its now mapped in to the ecu on at 43 Deg off at 38 Deg as 40 is the optimum. Remember U will need to mix the water with methnoll in winter to stop freezing as the pump is expensive
