Mercedes® K&N High-Flow Air Filter, 2007-2015

Airflow to your engine is one of the most critical areas affecting the performance of your vehicle and one of the easiest areas to upgrade. Original equipment air filters on new vehicles are generally very restrictive. This is due to their paper construction that actually limits engine breathing. That's why we recommend K&N, the leader in filter technology as proven by their heavy use in both on and off-road racing.
