How to Change Your Engine Air Filter (a 5-Minute Job)
By Colby · How-to · July 16, 2026 · 3 min read
From the garage
This is the job that first showed me how much shops mark up simple work. An engine air filter is a cheap part that snaps into place in about five minutes with no tools — and a shop will happily charge you fifty or sixty dollars to do it while your car's in for something else. It's the perfect first DIY: hard to get wrong, impossible to hurt anything, and you'll never pay someone else for it again.
Why it matters
The engine air filter keeps dust and grit out of your engine. A clogged one chokes airflow and dulls throttle response and fuel economy. Inspect it once a year and replace it roughly every 30,000 km (about 20,000 mi) — sooner if you drive dusty roads. Your car's exact interval is in its maintenance schedule (BoxKitz lists it per vehicle).
Find the airbox
It's the big black plastic box near the top or side of the engine, with a fat intake hose leading out of it. The lid is held on by some mix of spring clips, small screws, or a hose clamp.
Swap it
- Undo the clips or screws and open the lid — it usually hinges up or lifts off.
- Note how the old filter sits — which face is up.
- Lift the old filter out and wipe any leaves or grit out of the box.
- Drop the new filter in the same orientation, close the lid, and re-fasten it.
That's the whole job — no tools for most cars, or just a screwdriver.
Buy the right one
Filters are shape-specific, so order by your year, make, and model (BoxKitz lists the fitment). Stock paper filters are cheap and perfectly good; a washable/reusable filter is an option if you like the idea of never buying another.

A few airboxes use small screws or a clamp instead of clips — a basic set covers it.

Five minutes, no risk, real savings. If you've never turned a wrench on your car, this is where to start — then move up to the cabin filter and an oil change.
Guides are general advice for typical vehicles — your owner's manual is the final word for your specific car, especially on jacking points and torque specs. Work safely.
Frequently asked questions
How often should I change my engine air filter?
Inspect it yearly and replace it about every 30,000 km (20,000 mi), sooner in dusty conditions. Your vehicle's exact figure is in its maintenance schedule.
Is the engine air filter the same as the cabin air filter?
No — the engine air filter cleans the air going into the engine; the cabin air filter cleans the air you breathe inside the car. They're separate filters in separate places (see our cabin filter guide).
Can I just clean the old filter instead of replacing it?
You can tap out loose debris or gently vacuum a paper filter for a little more life, but if it's dark and clogged, replace it — they're cheap. Only oiled washable filters are designed to be cleaned and reused.
