When I increased boost I had my IC orings leak. I would loose some coolant each time I went wot and eventually the tank got pressurized to point where it leak coolant on the resevor cap.
I ended ordering cobra eng adapter that is a really nice piece but its pricy.. so far its been ok..
Key point is when installing the intercooler try to ensure is installed centered the holes give it some side to side play and could cause the oem IC adapter tubes and o rings to sit in an angle causing possibility for leaks..
I pressurized my IC tank and when removed blower there was 1 inch of coolant in the valley..
