AEM Dryflow Air Filters were developed in collaboration with K&N, the inventor of High Flow Air Filters. We adopted some of the best elements of cotton air filters into a new generation synthetic Dryflow Air filter. The three-dimensional filtering medium uses both depth loading and structural screen wire to enhance airflow capabilities and make the filter incredibly easy to clean. The result is a true performance air filter that does not require oiling, carries a lifetime limited warranty and is capable of increasing horsepower and torque.
