Improve Efficiency With Engine Air Filter Replacement

Your vehicle’s air filter is nestled under the hood and easy to overlook. Yet, a clean filter helps improve fuel economy and extends engine life.

There’s no warning when it is time to replace your engine’s air filter. It doesn’t make a fuss or send out alerts. And there’s no set schedule for replacement like its more prominent cousin, the oil filter.

Air filters usually need replacement after 30,000 miles. Check your owner’s manual for specific details on your vehicle and, if you are preparing for a road trip, contact your service advisor to find out when it was replaced.

Air filters, as their name implies, prevent airborne contaminants from reaching the engine.

In contrast, a sooty filter means particles such as dust can make their way into the engine and can cause friction.

Wear and tear reduces lifespan and makes your engine work harder. You may experience lower MPG.

Next time you visit your service center, ask your service adviser to inspect the engine filter. A clean filter can improve engine performance and longevity.

The National Institute for Automotive Service Excellence offers the following driver guidelines for engine air filters:

  • Going on a road trip? Contact your service center to find out the last time your vehicle air filter was replaced.
  • A clean air filter removes airborne contaminants such as dust and pollen, improving performance and MPG.
  • How and where you drive affect air filter replacement. Do you live near a ranch or in mountainous area or region with heavy smog? Chances are your vehicle air filter will need more frequent replacement than drivers living in a seaside town.
  • Learn more about all filters by checking your vehicle owner’s manual. Remember: Guidelines are affected by where and how you drive.
  • Consider replacing the cabin air filter at the same time you replace your engine air filter, especially if you are planning a long journey. Cabin air filters are critical for keeping air inside your vehicle healthy.
