Oil from a cotton filter can foul the mass airflow sensor, and the sensor reads wrong when it does. Dry filters remove that risk.
The Rugged Ridge dry panel air filter is made from woven synthetic fabric rather than cotton, so it passes air and traps particulates with no oil. It cleans with water instead of degreaser, which keeps maintenance cheap over the life of the Grand Cherokee.
