Air Filter Filtration & Engine Protection
K&N air filters offer an optimal blend of high air flow, filtration efficiency, durability and dust capacity. K&N high flow filter media has been tested in our own in-house laboratories and by independent labs using the ISO5011 air filtration standard developed by the Society of Automotive Engineers. Our goal at K&N is to design air filters with the most possible airflow while providing guaranteed engine protection.
K&N Air Filter Oil
A K&N air filter is designed with four to six layers of cotton gauze media sandwiched between two aluminum wire screens. The cotton media is then treated with a specially formulated grade of filter oil that causes tackiness throughout the cotton's microscopic strands. The cotton in a K&N air filter allows high volumes of airflow, and when combined with the tackiness of the filter oil creates an efficient filtering media that ensures engine protection.
