The 3/8" clip nuts will need to be installed in your frame rails prior to mounting the brackets. The front location (closest to bumper) circled in red below will need a clip nuts. If you have a non-turbo engine you will need to use (4) clip nuts, (2) per side. Insert them through the square hole in the frame and push until they snap into place over the smaller circle hole.
These brackets will be installed now on the frame rail. On the ecoboost models you will remove the bolt for the intercooler support bracket one side at a time. If you remove both sides the intercooler will drop down and could damage the hoses. Once the bolt is removed install one clip nut in the bolt location in front of the intercooler mount location. See image below for locations. Install with factory bolt on intercooler and provided 3/8 bolt and washer in front, leave loosely tightened for now so bracket can slide side to side.
Pro Tip: Using a flat head screwdriver and a small hammer can make installing the clip nuts a breeze!
