Description Reviews USED AEM DryFlow Hybrid Air Filter by K&N - AEM Dryflow Air Filters were developed in collaboration with K&N, the inventor of High Flow Air Filters. They've 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 and is capable of increasing horsepower and torque. Excellent filtration with great air flow Does not require oil Easy to clean Synthetic filter media NOTE - This filter is USED. It needs to be cleaned, but is in good shape.
