K&N Air Filter
From Wikipedia, the free encyclopedia
K&N Air Filter is an automotive air filter constructed of cotton gauze material, sandwiched between aluminum wire mesh. The filter was engineered to withstand repeated washings. To attract and hold dirt, the filter is treated with a specially-formulated oil. Introduced in 1969 by K&N Engineering, Inc., the company states that owners can drive for 50,000 to 100,000 miles between cleaning and claims a million mile warranty.
[edit] History
K&N Engineering, Inc. is headquartered in Riverside, California. K&N Engineering was founded by Ken Johnson and Norm McDonald. K&N Engineering quickly became known for its performance air filters for motorcycles and racing vehicles. K&N air filters were embraced by off-road racers, who experienced extreme conditions that quickly clogged the paper filters that were available at the time. K&N's filter technology was applied to automotive applications. K&N manufactures the majority of its products from raw materials on machines designed in-house. In addition to manufacturing, K&N's Research and Development facilities in the performance aftermarket include ISO Standard 5011 air filtration testing capabilities, engine and chassis dynamometers, air flow testing stations, and mass air meter (MAF) testing.
In its 36 years, K&N has continued to pioneer numerous improvements to its products. In addition to their washable/reusable High Air Flow Technology Filters, K&N offers several lines of cold air intake systems. K&N product lines include Fuel Injection Performance Kits, AirCharger Intake Systems, Typhoon Intake Systems, and High Flow Intakes.
[edit] Environmentally friendly
One of K&N's claims to fame is that its lifetime air filters never need to be replaced and do not end up in landfills or incinerators with more than 100 million conventional disposable paper air filters every year. Also, they are made of cotton, a renewable resource.
