Engine Air Filter Replacement Cost
Open the airbox, drop in the new filter, close the clips. Takes under five minutes and requires no tools on most vehicles.
What this repair is
The engine air filter cleans the air entering your engine, trapping dust and debris before they can cause wear. A clogged filter reduces fuel economy and power. It should be replaced every 15,000 to 30,000 miles, more often in dusty conditions.

Engine Air Filter Replacement FAQ
How often should I change my engine air filter?
Every 15,000 to 30,000 miles. Check it at every oil change by holding it up to light — if you can’t see light through it, replace it. Dusty or rural driving shortens the interval.
Does a dirty air filter affect gas mileage?
It can. A severely clogged filter restricts airflow, which can reduce fuel economy by up to 10% and hurt acceleration. On modern fuel-injected cars the effect is smaller than on older carbureted engines, but it’s still measurable.
Can I clean and reuse an air filter instead of replacing it?
Standard paper filters cannot be cleaned effectively and should be replaced. Some performance filters (like K&N) are washable and reusable, but they require special cleaning oil and re-oiling kits.
