Activated Charcoal Filter - It may be time to replace your Pollen filter, especially if you have allergies. This is the filter which brings clean air into the cabin of the car, and it should be replaced on a regular basis. Porsche recommends changing these every 20,000 miles or every four years (whichever comes first). In some areas, it should be replaced often.
Fits all Cayenne models, 2003-2010. Located under the dash, professional installation recommended.
