Time and Effort
Time: 5-10 minutes
Difficulty: Easy
Process
Tip: It’s best to be parked where you can comfortably open your passenger side door wide
Empty Glove Compartment
Take the stuff out of the glove compartment
Lower the Compartment
Remove Stop Arm
With the glove compartment open, look to the right side and locate the stop arm. Use a finger to pull it until it pops off
POP!
Press the Tabs
Then press the tabs on either side of the glove compartment to unhook the box
Tabs on either sideClose-up
It will swing downwards. Just leave it there. It doesn’t need to come out.
Note: If you didn’t unload the contents, everything gets dumped on the floor…
Open the Filter Cover
On either side of the uppermost, solid plastic, rectangular door are 2 tabs that keep it in place. Push aside (outwards) the plastic tabs until both sides free from the little tab. Be careful not to break anything!!
Hint: you may need to push aside any impeding wiring bundles.
The right was easy, but the left required two hands: one to push, and one to pull the filter door down
Here’s a close up of the left-side tab from my 2023 Mach-E. The wiring bundle butts up against the tab, making it difficult to remove. The 2024 was much easier without the wiring in the way as much
Push up or aside any wayward wiring bundles and reach your fingers (or a plastic pry tool) up and around the two sky-facing tabs. Pull carefully down to open the door
Warning: Be careful of the metal frame! It’s sharp!
Remove Old Filter
There it is! Just reach in, pull out the old air filter, and note the direction of the airflow arrow
Ta Da!
Place New Filter
Compared to the Motorcraft filter, the Purolator is much stiffer. Just position and slide it in
All Steps in Reverse
Close the filter door and press until you hear/feel the click on both sides
Pull the glove compartment back up into position until the side tabs click into place
Replace the stop arm on the side of the compartment by just giving it a nice push
PositionPUSH!Boom!
Put your stuff back in
All done!
YOU DID IT! Super easy, AND you saved yourself some money!
The 3rd/bottom hole does not have a factory guide dimple
Align and hold the frame to the car in line with the 2 dimples to use it as a template for bottom hole during installation
Find the plastic Pop Rivets that came with the frame. Push them through the frame and into the bumper
Slide the Rivet Gun over the part sticking out, and squeeze. This will compress the anchor back against the bumper. Release and squeeze again. You should hear a loud CLICK and the rod should come off (*See Notes for a look into how it works)
NOTE: You might have to squeeze a few times, making sure the gun is seated all the way against the frame. If it fails (the rod breaks off, but the rivet does not hold) push it out and try with the other rivet. In case this happens, and you don’t have a spare, make sure to do the top 2 holes first because the frame will hold fine with just two attachments.See Notes section for more information on the hardware
Slide the plate into the bracket, secure with screws
DONE!
Process: No-Drill
Pros: Removable, no holes drilled into bumper, no mar after removal
Cons: Not 100% secure, chance of losing plate and frame
WARNING: My first attempt at this failed after a month. At the time, it was installed in the cold winter weather, and I did not employ the use of an adhesion promoter/sandpaper. This is written with the revisions in place. *See NOTES section for my updates regarding success/failure
Make sure your license plate frame has enough surface contact areas to adhere it well to the car with 3M tape
This is the vehicle’s original plate frame
Go out to your car and dry-fit the frame according to the factory dimpling on the bumper
Using painter’s tape, mark out borders to help with aligning (Recommend using strips that attach to both the frame and the car for easiest aligning)
Install license plate to frame (Can do this as the last step, if you prefer)
The OEM hardware will not scratch the car, stopping short of the end of the holes
With 180-320 grit Sandpaper, use circular motions to rough up the surfaces where the tape will attach
Soak either a cotton pad or cotton ball with Rubbing Alcohol (higher percent will dry faster) or use alcohol wipes
Wipe down surfaces with the alcohol and wait for them to dry all the way
Open the Adhesion Promoter packet (I’d recommend gloves here) and wipe each contact point with a thin layer
Allow to dry (90-120 seconds)
Measure out and cut the VHB 3M Tape to the size you need for your plate
Apply the sticky side to the plate, leaving the other side of the tape (the one that will contact the car) still covered
NOTE: 3M’s instruction for this tape recommends heating up with a hair dryer if using in the winter. This tape is also moveable until compressed and moving it should not affect adhesion properties. Viscosity reaches maximum increase by 72 hours.
Recommended: partially remove the liners in the house before going outside. It can adhere tightly, so you may need to use tweezers if your nails aren’t able to get a good hold
Go out to your car
Dry fit the frame again, if you’d like
Use Rubbing Alcohol to wipe clean the install area of the car, making sure all foreign debris is removed (otherwise the tape will adhere to the debris instead of the car)
Wait until it it has evaporated
Peel off the liners from the mounting tape
Align with the painter’s tape
Press
Keep pressing with decent pressure for at least a minute (I did around 2-3 minutes. It was easiest with my feet while I messed around on a phone for a bit)
Remove the painter’s tape
I tugged and wiggled it. Firm and strong hold!
Done!
Notes
Update 2/27/25 (10 days later): Still holding strong and no problems! Been on the highway, through work zones, lots of potholes, speed bumps, took turns too quickly, and plenty of stop and go traffic. So far, so good.
Update 3/25/25 (1 month): FAILURE!! Went to walk the dog and found the license plate frame on the ground! Good thing it was at home. I’ve decided to leave the instructions and post, up, though, because I still think it’s doable with some revisions.
It’s important to note that all the 3M tape was still adhered well to the car. In fact, they were difficult to remove. Removal left a clean, unmarred surface — exactly the point of adhering as opposed to poking holes. This means that the failure point was on the side of the bracket, and not the tape or the car portion. I wonder if it was because the weather started to change. I installed it in the cold winter, and it fell off when the days warmed up and overnight.
Update 3/30/25: Compromise. While I did not want to risk the plate falling off again (what if it happens while on the road?) I still think that it’s possible to adhere with 3M tape without drilling. So, what I did this time was use the drill method for the top two holes and applied the revision process (adhesion promoter and sandpaper) for the lower hole. That way, I have it secure AND I didn’t drill into non-dimpled bumper. I will monitor and continue observing the bond of the lower portion of the frame at regular intervals to see if it holds up
Update 8/24/25: With the physical attachments, my bracket has not fallen off, of course. I went to try and tug on the bottom part of the frame where there is just the adhesion, and while it didn’t move much, I can’t really get a good read because of the hardware on the upper portion. At this point, I’m going to say that I do NOT recommend the No-Drill method, but you are welcome to try! If you do, comment and let me know if it works for you!
If you look at the wording on the back of the plate frame, you see the letters “PP+EPDM.” These stand for PolyPropylene (PP), plastic, and ethylene-propylene-diene monomers (EPDM), a synthetic rubber.

For fun, I tried it with double thickness to see what would happen. The first attempt failed, highlighting that if the ridged portion does not grab, then it will not stay in place and become loose. The second attempt succeeded but was extremely difficult to squeeze.
You can see how there’s more of the ridged part on the single thickness before it cut off
