K&N Universal Chrome Air Filter Includes Adjustable Flange Inserts

To meet minimum filtration standards, paper air filters must be thick and/or the fibers must be tightly compressed and dense. In order for it to provide adequate filtration, the paper filter must be more restrictive to airflow by design. As the paper filter becomes more and more clogged, the pressure inside the filter drops while the atmospheric air pressure outside the filter remains the same. When the pressure differential becomes too great, dirt particles can be pulled around the filter and paper medium. Foam air filters lack sufficient surface area and that hinders dirt holding capability. Open cell foam generally gets saturated with oil and dirt builds on the outside of the cell and blocks the openings. Higher vacuum pressure distorts the cells and draws the dirt deeper into the filter. Airflow is reduced as cells become blocked. K&N air filters feature four to six layers of cotton gauze that is treated with a special grade of filter oil that catches and holds the contaminants. Dirt particles are caught in the crisscrossed cotton fibers and the oil holds them in suspension. The air passes over the dirt particles trapped on the surface of the fibers and airflow remains high despite the build-up of dirt. Tests confirm that K&N air filters generally achieve overall filtration efficiency range of 96% to 99%. The K&N RG-1003RD-L air filter features a 4.5-inch large end diameter, base inside diameter of 2.75-inches and base outside diameter of 4.5-inches. The ultra-strong molded pliable rubber of the flange absorbs vibration and ensures a secure attachment. Moreover, this filter is washable and reusable. K&N offers an air filter cleaning kit that is specially formulated to cleanse the filter after 50,000 miles, depending on driving conditions. The cleaning kit also recharges the filter so that it can be reused for another 50,000 miles. If properly cleaned when it is supposed to be, the filter could be the last you will ever have to buy.
