  • 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.

Great quality and no lubricating like some other filters that affect the MAP sensor. Also, like the air intake sound.
