You won't have issues. The IC on the F150s is mounted on the bottom, so that bottom grill is where the air comes in for your IC. The S8 bar is slim enough that your upper fans will still have PLENTY of room to bring in air as well. We stock these and sell them all the time. Never had a single complaint (other then "hey I want to run 2 of these!")
