BMW Air Filter - BMC Air Filters E9X M3

Like your home's air filter, an engine's air filter is there to filter out dirt, dust and other foreign matter. Did you know that most of the dirt in your engine enters in through a dirty air filter? Your engine's air filter plays an important role as it prevents dirt from entering into the combustion chamber thus reducing the chances of internal damage and wear. A new air filter can increase airflow, improve overall engine performance, and in some cases add additional horsepower. Considering most of us drive in the harshest of conditions such as heavy idling in traffic, driving on dusty roads, and heavy towing, be sure to replace the air filter in your vehicle regularly.
