- For 2021+ F-150 models, the AGS Simulator assembly should have three ridges on the “back side”. If it does not, refrain from removing your bumper and contact support@velossatech.com immediately.
- Confirm that you have received a Driver Side (embossed with a “D”) and a Passenger Side (embossed with a “P”) bracket. Of the 2 holes available, use the hole furthest from the spline shaft for install (applies to both sides).
Stock Components Removal
Use Google or online forums to search for best practices when removing the
front bumper.
Cowl Templates
After removal of the grille/cowl assembly, you will need to use the supplied templates to drill ¼” holes in the locations shown. (Dual kits only have two templates).
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.
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, ensuring 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 adjust to the BIG MOUTHs to ensure they are level. Place the 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.
