Dropped my temps from about 60-70 above ambient temps with the K&N intake to about 20 degrees above ambient after.

while i agree that a true CAI/filter relocation is the best way to reduce IAT, i still think this might help
i wouldnt ever install the fan on the intake itself because it is nothing more than a fan and it will create a restriction since it will never be able to move air faster than what the engine can suck air in at but my basic idea was to have it mounted in front of the bumper(kind of like modshack's cold air ducts) where the inlets are for the intake(not on the inlet but in front of it or off to the side so airflow is not restricted)
it is a fan after all and if its on, it should in theory help reduce IAT
