How Often Should You Replace the Air Filter in Your Car?

It's one of the most overlooked maintenance items on any vehicle but a dirty air filter can affect your engine performance, fuel economy, and long-term reliability more than you might think. Here's what you need to know about your car's air filter and when to replace it.

What Does an Air Filter Do?

Your engine needs a precise mix of air and fuel to run properly. The air filter is what keeps dust, dirt, pollen, and debris out of your engine before that air gets mixed in. A clean filter means clean air and clean air means better combustion, better performance, and a longer-lasting engine.

Dirty Filter

How Often Should You Replace an Air Filter?

Most manufacturers recommend replacing your engine air filter every 15,000 to 30,000 miles, depending on your driving conditions. Here in the Yakima Valley and Tri-Cities area, dusty roads, agricultural environments, and dry summer conditions can clog a filter faster than average meaning local drivers may need to replace theirs closer to the 15,000-mile mark.

A good rule of thumb: have your air filter inspected at every oil change. It only takes a moment and can save you from bigger issues down the road.

Signs Your Air Filter Needs Replacing

Don't wait until your next scheduled service if you notice any of these warning signs:

  • Reduced fuel economy: A clogged filter restricts airflow, forcing your engine to work harder and burn more fuel
  • Sluggish acceleration: If your vehicle feels slow to respond, a dirty air filter could be the culprit
  • Engine misfires or rough idling: Restricted airflow can disrupt the air-fuel mixture your engine needs
  • Check engine light: A severely clogged filter can trigger fault codes in your vehicle's computer
  • Visible dirt or debris: If you pull the filter out and it looks dark and dirty, it's time for a new one
Clean Filter

Cabin Air Filter vs. Engine Air Filter

These are two different filters and both matter. The engine air filter protects your engine from debris. The cabin air filter cleans the air coming into your passenger compartment through the heating and cooling system. Both should be inspected regularly, and both are quick, affordable replacements when the time comes.
