Stock Components Removal
Remove the top 4 AGS flaps to allow clearance for the BIG MOUTH intakes. You can flex these flaps at their center, and then bend them outward to unhook the engagement pegs. See below.

AGS Simulator
This assembly was engineered and tested to allow the AGS to continue to function, which
will prevent a soft code from showing up on the dash for some 13th gen F-150 models.

60mm long M3 bolt, insert into the driver side "D" splined shaft and thread into the other splined shafts through the AGS motor, make a sandwich.
The `ear' of the supplied splined shaft should be facing up away from the grille. BOTH EARS SHOULD BE POINTING IN THE SAME DIRECTION.

AGS Simulator
Use Allen key to fasten the sandwich together, tighten until snug, do not over-torque.

AGS Simulator
Finalize the assembly by screwing the 5mm bolt into the ears, ensure they bottom out and go through the AGS peg-holes as shown. (You can manually move the AGS to align the peg holes).
The AGS motor should now be locked to the AGS flaps through the splined shaft sandwich and 5mm screws.

AGS Simulator Testing
Once the AGS Simulator install is complete, temporarily reinstall the bumper (no need to fully fasten yet), reconnect the AGS motor, turn your car on and allow the AGS system to perform its initiation cycle. If your flaps successfully open and close without interference, the install is successful and the AGS is fully functional.

The AGS flaps should complete a 180° cycle

Assemble BIG MOUTH Ram Air
From underneath the cowl openings, align the BIG MOUTH ram air intakes with the holes drilled, and fasten with supplied button head screws. For dual kits, use the provided spacer on the lowest outer ear to avoid stressing the Big Mouth.

Finalize
You can make an adjustment to the BIG MOUTHs to ensure they are level. Place bumper on the vehicle however do not fasten it yet, inspect visually for alignment and level of your BIG MOUTH intakes. If you need more adjustment, go back and drill bigger holes in the shroud to allow play room, then tighten as needed. You may add shims between the cowl shroud and the BIG MOUTH fastening points to help with leveling for your particular vehicle.
