I'm swapping a 12v from a 98 into my 1973 IH pickup. The steering box is right where the intake pipe from the intercooler would go in the dodge ( box is outside the frame instead of inside like a 98 dodge ) the inter cooler seams too fit if i flip it upside down and have the outlets on top. This would reverse the air flow from the stock configuration. Will the air flow through it as well as stock or are they built to be directional with the air flow? Any help is appreciated
