Follow these steps carefully
Park on level ground, engine off, and open the hood. This is a clip job from start to finish — Mazda's SkyActiv airbox needs no tools at all.
Find the two metal hinge clips on the front of the airbox. Don't pry them with a screwdriver; they bend easily, and a bent clip won't hold tension when you close it back up.
In my experience, small thing, big difference: Don't pry them with a screwdriver; they bend easily, and a bent clip won't hold tension when you close it back up.
Lift the lid up and forward. Lift the old filter out and note which way it faces so the new one matches.
Vacuum or wipe out the lower half of the box — pine needles and grit collect in the bottom. Wipe the underside of the lid. Check the two clips for cracks and make sure the lid's sealing edge isn't warped or chewed up.
I've been burned enough times that I always do yourself a favor here: Check the two clips for cracks and make sure the lid's sealing edge isn't warped or chewed up.
Set the new filter into the lower half the same way the old one sat. Press around the perimeter so the rubber frame seals flat against the box — the filter shouldn't rock or lift at a corner.
Set the lid back on rear-first: slide the back tabs into their slots, then lower the front. Swing both metal clips back down and press them until they snap locked.
Start the engine and let it idle. No warning lights should appear. Once you've done it once, this is genuinely a five-minute job.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
