  • Excellent filtration with great air flow
  • Does not require oil
  • Easy to clean
  • Synthetic filter media

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.

I am very pleased with the AEM DryFlow Air Filter. It is very durable as I have personal tested it. (Totaled my car and the only thing damaged was the filter itself...The assembly was unharmed.) I would recommend this product to increase performance without a lot of hassle.
