Engine Protection Filtration
Anyone can flow more air. The trick is to flow more air safely. K&N have hit the sweet spot - an optimal blend of high air flow filtration efficiency durability and dust capacity.

The Importance of Oil
A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminium wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton's microscopic strands. The nature of the cotton allows high volumes of airflow and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection. In contrast most other media can not maintain the same balance of airflow and filtration throughout the filter's life without sacrificing one or the other. With a K&N Air Filter there is no sacrifice! Since 1969 K&N Engineering has been designing manufacturing and enhancing High-Flow Air Filters for the motorcycle enthusiast.
