Follow these steps carefully
Trace the black intake tube from the throttle body forward to the square airbox between the headlight and strut tower. The 3.7L V6 was the only engine offered — no fitment split. Count the lid's spring clips now so you relatch every one later.
Flip each spring clip up off the lid's lip, then lift the top half straight up — don't hinge it sideways, which crimps the filter edge. If the lid resists, wiggle front to back; the rubber intake boot flexes enough.
That straight-up lift matters more than it sounds. I crimped a brand-new filter on my first one of these by hinging the lid like a door — heard the whistle on the test drive and had to redo the whole thing.
Lift the old element out, noting orientation — pleats one direction, gasket down. Check for damp spots or musty smell; this low box can collect splash water, and a wet filter means checking the housing drain. Set it aside pleats-down.
My nose catches this before my eyes do: Musty smell plus a damp filter? Don't just swap and go — find where the water's coming from. Nine times out of ten it's the housing drain clogged with leaves.
Wipe the lower housing and cover underside with a rag — a good seal needs clean mating surfaces. Clear grit from the sealing channel around the lower rim; packed grit holds the new gasket off its seat. Check for cracks, especially around the clip ears.
Set the new element gasket-down into the sealing channel. Don't crimp the edges between housing and cover — a crimped edge lets unfiltered air into the engine. Press evenly so it sits flat, then lower the top half straight down without sliding.
Press the cover down and re-engage every clip, working around the box — don't latch one side fully then force the other, or you'll pinch the gasket. Run a finger along the seam; it should be uniform, nothing standing proud.
Start up and listen for whistling at the airbox — that means a pinched gasket or unlatched clip. Confirm steady idle, no warning lights. No hard mileage interval: inspect at every oil change, replace when dirty, more often on gravel or dusty roads.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
