Follow these steps carefully
With the engine cold, open the hood. The airbox sits in the right front corner — a box with a flexible hose to the engine. Same hinged-clamshell design across the 2004–2009 run, 3.6L V6 and 4.6L Northstar V8.
Remove the two screws on top of the cover — they're the only fasteners. Keep them safe: the lid can't seal without both, and they're easy to knock into the bay. A magnetic tray is worth it here.
Disconnect the coolant recovery hose where it runs across the top of the airbox, per the owner's manual, and move it aside so it's clear of the lid. You're not draining anything — don't open any coolant fittings.
The box halves hinge at the bottom — push the top of the cover toward the engine to crack it open like a book, filter between the halves. Don't lift the cover off; you'll stress the plastic.
Lift the old filter straight up through the opening and note its orientation. The manual calls for inspecting the filter at the Maintenance II intervals and replacing it at the first oil change after each 50,000 miles.
Shake the old filter gently before you bin it. If loose dust won't fall free and the pleats are still caked, it was overdue — and I'll check the box for a dust trail to make sure the seal was holding.
Wipe out both halves and check the lid's sealing edge for grit — clean plastic keeps the clamshell airtight. Drop the new filter into the lower half so it sits square, oriented as the old one was.
Swing the cover closed and reinstall the two top screws. Lay the coolant hose back across the box and close the hood. Never drive with the air cleaner off — it stops flame in a backfire.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
