Your Porsche has two air filters: an engine air filter and a cabin air filter. They work much like your fuel filter and oil filter do in that they're responsible for capturing contaminants. In the case of your air filters, those pollutants are airborne, and can include pollen, dirt, debris, insects, allergens, and even sand.
The engine air filter keeps the contaminants out of the air intake and your engine parts. Your cabin air filter keeps prevents them from getting into your passenger space via the air ducts and vents.
Eventually, though, those pollutants can restrict airflow through the filters. If that doesn't happen, they'll wind up degrading with age. When either happens, you can expect engine trouble and HVAC issues. Replacing your air filters can prevent that from occurring.
How to Tell That Your Air Filters are Going Bad
Signs of failure include:
- Reduction in horsepower
- Misfiring engine
- Darker coming exhaust emissions
- Inconsistent cabin air temperatures
- Cabin smells musty
- Whistling sounds coming from the air vents
Choose Genuine Porsche Air Filters
If you're not experiencing any issues, check your owner's manual for your recommended maintenance schedule. Both should be changed at least every 30,000 miles, though road and environmental conditions can affect that number. Make a habit of checking your filters' condition regularly; if you're unable to see light through them, or they look ragged, then they need to be changed. The air filters that your manufacturer makes are designed specifically to fit your model, providing the guaranteed compatibility that you want and need. Find yours in our online auto parts inventory.
