AEM DryFlow Air Filter AEM 3 in x 9 in Dryflow Air Filter AEM DryFlow Air Filt Air Filter 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. AEM Dryflow Universal Clamp-on Air Filters are washable synthetic air filters designed for a high-efficiency combination of air flow, filtration, and performance. AEM Dryflow filters use an innovative high performance oil-free filtration material that allows easy cleaning, durable service, and excellent filtration. This clamp-on universal air filter has a filter top for higher air flow capability making it great for everyday use.
