So originally I was planing on running a tube from the air box to the grille for cooler air. Was seeing IAT temps while driving at about 112° last week. Ambient temp was around 98-102° Took the truck out for a drive today and ambient temp was 91-92° and saw IAT between 93-95°. Only difference was the fan controller. Must be helping keep my engine bay temps lower. Very surprised how well that is working. Stock 6.4 air box pulling from the fender behind the headlight.
