Two filters keep air clean. One protects the engine. The other protects you. Both are cheap and easy to replace yourself.

Engine air filter
A clogged filter restricts airflow and can reduce power and economy slightly. Replace it every 15,000 to 30,000 miles.
| Filter | Interval | Typical part cost |
|---|---|---|
| Engine air | 15,000 to 30,000 mi | $15 to $30 |
| Cabin air | 12,000 to 15,000 mi | $12 to $30 |
| Oil filter | Each oil change | $5 to $15 |
| Fuel filter | Varies, many are lifetime | $20 to $60 |
Intervals and costs are typical ranges. Your owner’s manual comes first.
Cabin air filter
It cleans the air that blows through the vents. Replace it yearly or when airflow weakens or the cabin smells musty.
Clean air is cheap.
Doing it yourself
Most cars hold the filters in a clip-open box. A shop can charge several times the price of the part for the same job.
Do it in this order
- Look up the part number
- Watch a video for your car
- Check the old filter
- Replace on schedule
Practical tip
Shops often charge $60 to $100 to swap a cabin air filter. The part is $15 and the job takes five minutes.
Bottom line
Swapping filters yourself saves money and takes very little skill.
Specifications, prices and rules change. Confirm current details with the manufacturer or the relevant authority before you buy or repair.
