How Often Should I Change My Engine Air Filter?

Air filters are an essential component of your car, SUV, or truck, and you should never disregard them. The air filter blocks dirt, debris, and other impurities from entering the engine chamber and helps provide pure airflow. You should replace your engine air filter every 15,000 to 30,000 miles on average.

 

Your car engine relies upon its air filter to prevent dust and debris from disrupting the engine's processes. By providing clean airflow to the engine, an air filter ensures the engine gets the right amount of air when needed.

 

Worn, dirty, or clogged air filters can cause your engine to perform unsuccessfully. For instance, you might notice that your car has less power or weaker acceleration if you haven't changed your engine air filter in a while. But how do you know when it's time to renew your engine air filter?

 

A straightforward way to do it is to keep track of how long or how many miles you've driven since your previous filter change. If it's been more than a year or two, it's your best bet to change it. If you often drive in high-traffic locales or do a lot of stop-and-start driving regularly, your air filter may get dirty quicker. Operating in dusty or rural locations can also make your air filter decline faster. Lastly, you can determine when you need to replace your air filter by looking out for some of these telltale signs of a dirty or clogged filter: 

  • Dirty or dusty appearance from the filter itself
  • A lack of acceleration power
  • Unusual engine noises
  • Engine-related issues, including misfires 
  • Lower fuel economy
  • Black, dense exhaust smoke emitting from the tailpipe
