Engine and Cabin Air Filter Replacement: The Easiest DIY Savings

Air filters are some of the easiest parts to replace yourself, and they're often upsold at service visits. Follow the replacement interval in your owner's manual, and replace sooner if you drive in dusty conditions.

Engine air filter

  1. Find the airbox, a plastic housing connected to the intake tube.
  2. Release the clips or screws and lift the lid.
  3. Note the filter's orientation, remove it, and wipe out the housing.
  4. Install the new filter so it seats fully, then close the lid securely. Air leaks let dirt bypass the filter.

Cabin air filter

It's usually behind the glovebox, which unclips or swings down. Some vehicles put it under the cowl at the base of the windshield. Check the airflow arrow and install it in the correct direction.
