Since 1969 K&N Engineering has been designing, manufacturing, and enhancing High-Flow Air Filters for the automotive and motorcycle enthusiast interested in maximizing horsepower and acceleration. Since their humble beginnings K&N has designed and manufactured over 2,400 High-Flow Air Filters to fit most modern passenger vehicles and over 500 High-Flow Air Intake Systems to fit vehicles driven by enthusiast minded drivers. K&N not only has more applications than any other manufacturer of similar product, they invented the High-Flow filter category and the High-Flow Technology that supports it. K&N also makes thousands of racing and specialty type air filters and is the only air filter used at the Indianapolis 500.

The K&N FilterCharger® air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. K&N automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret of K&N's success lies in the unique characteristics of the filter medium that was originally developed all those years ago in the dust, sweat and tears of desert motocross racing. K&N just wanted to win races and stumbled on a cotton filtration technology destined to be great. The high flow cotton gauze FilterCharger® air filter is washable, reusable and built to last for the life of an automotive 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 enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to 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 protect your engine for the life of your vehicle
