Step-by-Step Instructions

Follow these steps carefully

Park, cool down, and pop the hood

Park on level ground, shut the engine off, and set the parking brake. Let the 4.0L V6 cool for a few minutes. Pull the hood release under the dash, release the secondary latch at the grille, and prop the hood open.

🔧 Mechanic's note — Tom Becker

I give the FJ a few minutes of cool-down every time — these bays run hot and the airbox plastics are right in it.

Locate the airbox on the passenger side

Find the black plastic airbox on the passenger side of the bay — the wide, ribbed intake duct to the throttle body marks it. Confirm it's the filter box, not the fuse or relay boxes.

Flip open the two front locking clips

Two metal locking clips hold the lid's front edge — flip each outward and up; no tools needed. The rear edge isn't clipped; it rides on hinge tabs, so don't pry at the rear.

🔧 Mechanic's note — Tom Becker

I've seen people pry at the rear edge like it's clipped and crack the hinge tabs. If it won't lift, you missed the clips — look again at the front.

Hinge the lid up and lift out the old filter

Tilt the lid up from the front and lay it back gently without straining the duct or MAF wiring. Lift the old filter out of the lower tray, noting which face was up and how the rubber frame sat.

Clean out the lower airbox tray

Vacuum or wipe leaves, grit, and sand from the lower half with a clean rag. Check the intake duct opening for debris. Do not push dirt toward the engine side, and do not blow compressed air into the open intake.

🔧 Mechanic's note — Tom Becker

FJ airboxes fill with fine dust — I vacuum the tray twice because the first pass always misses the corners.

Seat the new filter in the lower tray

Lower the new filter in like the old one, with the rubber frame lying flat in the tray all the way around. Press gently so it settles evenly — a crooked filter keeps the lid from sealing and lets dusty air bypass the media.

Set the rear tabs, relatch, and test

Swing the lid down, hooking the rear tabs into the back brackets first, then flip both clips closed until they snap. Check the seam for gaps, close the hood, and start the engine — listen for whistling that signals an air leak.
