Air Filter - Porsche recommends checking the air filter at regular inervals, and replacing them every 40,000 miles. Make sure you're not choking your engine for air! Chose the standard filter (recommended), or optional "thick" filter for use in dusty / sandy regions outside USA.
Note: This comes with ONE air filter required for the 2011-2018 Cayenne (V6), Cayenne Diesel, and Cayenne Hybrid models.
