How Often Should You Replace Your Engine Air Filter?

August 7, 2025

Keeping your engine breathing clean air is one of the simplest ways to protect its performance and longevity. Yet, engine air filters are often overlooked when it comes to routine maintenance.


At Joe’s Slinger Service in Slinger, WI, we regularly inspect and replace air filters for drivers across all of Washington County and surrounding areas—here’s what you should know.


How Often Should You Change Your Engine Air Filter?


Most manufacturers recommend changing your engine air filter every 15,000 to 30,000 miles. However, that interval can vary based on:


  • Local driving conditions (dusty roads, farm areas, construction zones)


  • How often you drive in heavy traffic


  • Towing or hauling loads


  • City vs. highway driving


If you’re driving in rural Wisconsin roads or commuting through stop-and-go traffic, your filter may clog faster, meaning it should be checked more often—about every oil change or every 6 months.


Why It Matters


A dirty or clogged air filter can:


  • Reduce fuel efficiency


  • Decrease engine power


  • Trigger your check engine light


  • Increase harmful emissions


Swapping in a new engine air filter is quick, affordable, and improves both performance and peace of mind.
