Air Filters

Refine Results

Air passes through your Audi every day. It carries contaminants like dirt, dust, and allergens with it as it travels. They can build up in its air intake, on its fuel injectors and spark plugs, even in its ducts and on its vents -- that is, unless your Audi has OEM air filters installed.

What an Air Filter Does

Air filters help keep airborne pollutants from accumulating in your heater and air conditioner and on engine parts. Your Audi has two: a cabin air filter for its HVAC system and an engine air filter for its motor. In short, the filters help both work as well as they can.

Unfortunately, a filter can choke with debris and stop working as well. They can also wear out from old age. When they do, other issues follow. Luckily, there are signs you can look for to tell you it's time for a change.

Signs Air Filters Need Replacing

  • The Check Engine light on your dash is lit
  • Your filters are dirty, congested, or degraded
  • Your cabin smells unclean
  • Your engine's stressed, making unusual noises, or misfiring
  • Your fuel efficiency is worsening
  • Your vehicle's emissions have increased significantly
  • Your heating and air conditioning systems are malfunctioning

To help avoid these problems, be sure to replace both air filters regularly.

When to Change an Air Filter

Your owner's manual will likely recommend replacement every 12,000 to 15,000 miles but double-check its maintenance schedule to be sure. If you're seeing any of the listed symptoms, however, more than likely, it's changing time.
