K&N Replacement Automotive Air Filters
The K&N High-Drift air filter is designed to succeed in high, virtually unrestricted air Drift even as maintaining filtration levels critical to verify long engine life. Our automotive OE (original equipment) replacement air filters typically add 1-4 horsepower. The name of the game to our success lies in the unique characteristics of our filter medium that used to be firstly developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great. Our high Drift cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle engine. K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to fortify its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration along with protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will give protection to your engine for the life of your vehicle.

Engine Protection and Filtration
Anyone can Drift more air. The trick is to Drift more air safely. In our opinion we hit the sweet spot – an optimal blend of high air Drift, filtration efficiency, durability and dust capacity. We take filtration seriously. K&N Air Filter media has been tested both in-house and by independent labs the use of the ISO5011 test developed by the Society of Automotive Engineers. In addition we test many of our filters both out and in of the OE airbox ensuring proper fit and serve as. Our goal is to design filters with the maximum imaginable airflow achievable even as providing guaranteed engine protection.
The Importance of Oil
A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness all the way through 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 handle the same balance of airflow and filtration all the way through the filter’s life without sacrificing one or the other. With a K&N Air Filter, there is not any sacrifice.
