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. Their automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to K&Ns success lies in the unique characteristics of their filter medium. Their high flow cotton gauze air filter is washable, reusable and built to last for the life of your 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.
With K&N, engine protection by filtration is as important as airflow. Anyone can flow more air. The trick is to flow more air safely. K&N Air Filter media has been tested both in-house and by independent labs using the ISO5011 test developed by the Society of Automotive Engineers. K&N designs filters with the maximum possible airflow achievable while providing guaranteed engine protection. In contrast, most other media can not maintain the same balance of airflow and filtration throughout the filters life without sacrificing one or the other. With a K&N Air Filter, there is no sacrifice.
Handmade in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable. Regardless of what youve heard, its almost impossible to wash your K&N Air Filter too much. Inside their testing laboratory, they have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification. Depending on your driving conditions, we recommend cleaning your air filter every 50,000 miles. To clean and re-oil, purchase the K&N filter Recharger service kit and follow the easy instructions.
