When do you replace the air filter on Acura MDX?

You should replace the air filter on an Acura MDX approximately every 15,000 to 30,000 miles, or at least once a year, depending on driving conditions and environment. If you often drive in dusty or polluted areas, more frequent changes may be necessary. Always consult the owner’s manual for the specific recommendations for your model year. Regularly checking the filter for dirt and debris can help determine if it needs replacing sooner.
