Products
K&N's air filter is an automotive air filter constructed of cotton gauze material sandwiched between aluminium wire mesh. It allows more air to flow in freely while dirt and particles stick to the oil. K&N assert this configuration is more efficient than paper filters, resulting in more oxygen gets into the engine, allowing vaporized fuel to burn more efficiently, thus increasing horse power and fuel economy.[ The filter is periodically washed and then coated with an oil, also supplied by K&N. The company states that owners can drive for 50,000 to 100,000 miles between cleaning and offers a million-mile warranty.
