Dirt, debris, dust, pollen… these contaminants and more pass through the engine parts and HVAC system in your Audi every day. Your factory Audi air filters capture them. If you didn't have both types -- an engine air filter and a cabin air filter -- all that crud would cause problems. It'd get into your throttle body. It'd deposit on your air intake and spark plugs and gunk up your carburetor or fuel injectors. It'd even accumulate in your heating and air conditioning systems' ducts and on their fans and vents. When that happens, parts degrade double quick.
Clogged air filters are another problem. Engine filter blockage forces an engine to burn more air and fuel than it needs to. That results in engine performance issues like misfires, higher emissions, and lower fuel economy. Cabin filter blockage cuts airflow. This makes it harder for your heater and air conditioner to get your interior temperature right. Cabin air quality suffers, and worse, your motor stresses. Luckily, you can avoid all of this.
Learn to identify Failing Air Filters
Just be sure to change your air filters regularly. It's easy to tell when you should. Aside from a lit Check Engine light, look for brittle, discolored, or mucky fibers. Unusual engine noise and excessive exhaust smoke indicate the need to replace your engine filter. Unpleasant odors indicate the need to replace your cabin filter. If you're still unsure what to do and when, review the filter maintenance schedule in your owner's manual.
