Products

K&N's air filter is an automotive air filter constructed of cotton gauze material sandwiched between aluminium wire mesh. The filter is periodically washed and then coated with an oil also supplied by K&N. The company states owners can drive for 50,000 to 100,000 miles between cleanings, and offers a million-mile warranty. The company claims this construction allows more air to flow while dirt and particles stick to the oil, and asserts this configuration is more efficient than paper filters, resulting in more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently, thus increasing horsepower and fuel economy. However, independent tests call the of these claims into question [ [http://www.bobistheoilguy.com/airfilter/airtest1.htm Comparative automotive air filter flow & filtration tests] ] . K&N also asserts its air filters are more environmentally friendly than ordinary filters, since they never need to be replaced and thus do not end up in landfills or incinerators.
