AGS Simulator Installation:
- Insert the 60mm long M3 bolt into the driver side D splined shaft and thread it into the other splined shafts through the AGS motor.
- Ensure both ears of the supplied splined shaft are facing up away from the grille and in the same direction.

- Screw the 5mm bolt into the ears to lock the AGS motor to the AGS flaps through the splined shaft sandwich.
AGS Simulator Testing:
After installation, temporarily reinstall the bumper and reconnect the AGS motor. Turn on your vehicle to allow the AGS system to perform its cycle. If the flaps open and close without interference, the installation is successful.

Align the BIG MOUTH ram air intakes with the drilled holes from underneath the cowl openings and fasten them using the supplied button head screws. Use a spacer for dual kits on the lowest outer ear to avoid stress.
Final Adjustment:
To ensure proper alignment, visually inspect the level of your BIG MOUTH intakes with the bumper placed on the vehicle. Make adjustments as needed by drilling bigger holes in the shroud for playroom or adding shims for leveling.

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