Abstract
An air filter arrangement is suitable for a combustion engine that is built into a motor vehicle. The combustion engine has opposite rows of cylinders and its air filter device includes an air filter housing that receives an air filter and has two inlet connection pieces. To optimize the air filter arrangement, the inlet connection pieces are connected to the raw air chambers of the air filter housing, which are connected with a clean air chamber via the air filters. A feeder line is run to the combustion engine from that clean air chamber. The raw air chambers are disposed closer to the engine than the clean air chamber.
