We have used K&N filters for decades on all our vehicles. We replace the manufacturer filters as soon as we purchase a vehicle.

aFe Pro-Dry S review

Reviewed By Charles T (Saint Simons Island, GA) Reviewed for a 2014 Mercedes-Benz E-Class —7/20/2019 10:50 AM

Have had three aFe Pro-Dry S air filters in three M-B's. The aFe filters have always resulted in a notable improvement in throttle response, if one is not just plodding around town, a pleasing low rumble-growl during acceleration, and a minor improvement in gas mileage. A simple way to make a genuine upgrade. Putting one in any car that is performance oriented, even to a minor degree is S.O.P. for me.
