How Often to Change an Engine Air Filter

replacing cabin air conditioner filter of car

Your engine relies on a constant inflow of fresh air in order to deliver the performance you depend on, and you need to know how often to change your engine air filter if you want to keep your model at its best. Most experts recommend an engine air filter replacement interval of roughly 30,000 to 40,000 miles, but you should always check your owner’s manual for a model-specific recommendation. 

Any questions? Explore other service tips or give us a call at (855) 552-1309 to find out when your filter is due for replacement.

What Does an Engine Air Filter Do?

Maybe you bought your vehicle used, or you’re not sure when your current engine air filter was installed. Having an idea of what your air filter actually does can help you recognize problems and schedule service before they become major issues:

  • An engine air filter prevents contaminants from reaching the most sensitive parts of your engine, where they can build up and cause malfunctions.
  • A clogged and dirty engine is going to deliver less power to your drivetrain. It will also limit your fuel economy.
  • The engine air filter is distinct from the cabin air filter, which keeps particles and allergens out of your interior. Both filters need to be replaced on occasion, but not necessarily at the same time.

The symptoms of a failing engine air filter are as follows:

  • Misfiring spark plugs or slow start-up
  • Significant amounts of black smoke from the exhaust
  • Less satisfying acceleration, harder to pass other drivers
  • Lower fuel economy and more trips to the pump
  • Lit-up check engine light

Keeping up with the recommendations in your owner’s manual can prevent issues for most drivers, but how often should you change your engine air filter in hot, dry, dusty climates? Since environmental factors can play a role in determining how long your engine air filter lasts, it’s a good idea to schedule this service more often.

Engine Air Filter Replacement

Although we’re happy to take care of engine air filter replacement as part of your regularly scheduled maintenance, some drivers find that it’s easy to handle this job at home in Greenwich or New Canaan. Here’s how it’s done:

  1. Pick up a new engine air filter from our parts department. Check your owner’s manual or ask our team if you’re not sure about which filter to use.
  2. Reference your owner’s manual to determine the location of your engine air filter. (It’s usually under the hood, close to the front of the engine compartment.)
  3. Put on a mask and use gloves to remove the filter! After all, you don’t want to inhale any of the particles that may escape during the process.
