Many K&N replacement air filters feature a multilayered cotton gauze media that has been treated with a special grade of oil that makes the strands of the cotton very sticky. The filter is designed to encourage high airflow with superior filtration. As more and more contaminants are captured, the airflow continues to pass through the cotton gauze with little if any restriction. Tests confirm that the overall filtration efficiency of the filter is in the range of 96% to 99%. Each K&N air filter is designed to boost horsepower, acceleration, and torque and lasts for at least 50,000 miles between cleanings.

Meanwhile, conventional paper air filters have a very thick surface area and are tightly compressed and dense so that they can meet the minimum filtration standards. This design restricts airflow. As the paper filter becomes more and more clogged, the air pressure inside drops while the pressure outside remains the same. This results in an excessively high pressure differential causing the dirt particles to push through the paper medium. Airflow decreases even more making it necessary to replace the filter.

On the other hand, conventional foam air filters lack appropriate surface area, which limits dirt holding ability. Dirt builds up on the outside of the foam filter and blocks openings. This results in higher vacuum pressure that distorts the cells and draws more dirt deeper into the filter. Airflow is restricted even more as the cells become clogged.

K&N also offers air filters with a synthetic non-woven material that are ideal for a wide range of applications including small industrial engines, compressors, generators, utility lawn, garden units and mowers as well as for heavy duty applications including large turbo diesel engines, class 6-8 over-the-road trucks, agricultural and earth moving equipment and diesel motor homes.

The commercial grade air filters include a new hybrid medium that combines the best characteristics of cotton and synthetic non-woven technologies. No oil is used in these filters. Instead, they feature a 3-D lofted filter surface that reduces diesel air filter restrictions. The result is more power and better engine efficiency.

K&N air filters for heavy duty commercial grade applications feature extra strength construction and are reinforced to last for up to 300,000 miles. These hybrid filters feature a thick lofted non-woven synthetic media that is co-pleated between two layers of powdercoated aluminum screen wire. The media is sandwiched between either molded urethane or steel plates and surrounded by a powdercoated steel cage to withstand extreme temperatures and pressures that can occur in large turbo diesel applications.

K&N offers air filter cleaners and filter cleaning accessories for its lines of oiled cotton and synthetic air filters. The cleaners are specially formulated to cleanse and recharge the filters so that they can be reused over and over again.

K&N backs the oiled cotton replacement air filters with a 10-year/Million Mile Limited Warranty that guarantees that the filter will last for up to 10 years or 1,000,000 miles without needing replacement.

In addition, K&N offers cabin air filters that are designed to clean and refresh the passenger compartment of most cars. The filter is electrostatically charged to capture and hold all sorts of smelly and unhealthy contaminants including mold, mildew, pollen, spores, fungus, and germs.

The cabin air filters are designed to replace the factory cabin air filter from the cabin air filter box that is located under the hood, near the windshield, underneath the dashboard, or behind the glove box.

As in the case of the air filters, K&N also offers a cleaning kit that is formulated to recharge and cleanse the cabin air filter after every 12 months or 12,000 miles of driving, depending on driving conditions, so that it can be used over and over again for the life of the car.

The filters are designed to fit the factory air box and can be installed using common hand tools in just a few minutes.

Air filters can be found by part number or by vehicle manufacturer.
