Time and Effort

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

Press the Tabs

• Then press the tabs on either side of the glove com­part­ment to unhook the box

• 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

---

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

• Put your stuff back in

---

All done!

YOU DID IT! Super easy, AND you saved your­self some mon­ey!
