Cotton Air Filter Fibers
At K&N, our high-flow cotton air filters are made of four to six layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a special grade of K&N oil causing tackiness throughout the cotton's microscopic strands. The nature of the cotton allows high volumes of air to pass through the filter, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection.
Over 800 different replacement cotton media air filters for virtually every vehicle on the road.
