Engine Air Filter Replacement

Easy

Engine air filter replacement involves swapping out the old, dirty air filter element with a clean new one. The air filter prevents dirt, dust, and debris from entering the engine. A clogged filter restricts airflow, reducing engine performance and fuel efficiency.

Step-by-Step Instructions

1

Locate the air filter housing — it is typically a large plastic box near the top of the engine connected to the intake duct.

2

Unlatch the clips or remove the screws securing the air filter housing lid.

3

Lift the lid and remove the old air filter. Note the orientation of the filter.

Tips & Warnings

  • Check your air filter every oil change and replace it every 15,000-30,000 miles or as specified in the owner's manual.
  • Hold the filter up to a light — if you cannot see light through it, it needs replacing.
  • Do not use compressed air to clean a paper filter as it can tear the filter media.
  • A high-quality aftermarket reusable filter can save money over time but must be cleaned and re-oiled periodically.
