Facts about air filters
The primary function of an air filter is to clean the air before it enters the engine. If this is true, why do we see so many engines, especially expensive competition engines, without air filters? The answer is airflow. An engine’s power output is proportional to the volume of air it can ingest at any given rpm, assuming the fuel management system is capable of sustaining a near perfect air/fuel mixture ratio. The minutest restriction in the air induction system will cause an engine’s optimum power output to drop.
Maintaining optimum, unrestricted flow becomes a problem when the air must pass through a filter element. Conventional paper elements are very resistant to air flow because the filter material or medium is very dense. The greater the restriction the greater the power loss will be.
K&N engineers have made vast improvements in performance, durability and serviceability by directly addressing these inherent compromises. In the late ‘60s, K&N developed an oil impregnated cotton air filter gauze which exceeded the minimum filtration standards while offering little restriction to air flow. As a result, the first K&N filter element was manufactured by sandwiching several layers of surgical gauze between two sheets of wire mesh. The medium was then pleated to reduce the filter’s overall size and to increase its surface area. Finally the cotton gauze was oiled to enhance it’s filtering capabilities. The original concept exists today and after many refinements has evolved into the component used in our automotive, industrial, marine and motorcycle air filters.
K&N’s oil-impregnated, cotton-gauze element is the basis of our filter, as well as K&N’s overall dominance of the reusable air filter market. To further make the point, consider that square inch per square inch, our filter will flow at least 50% more air than the average paper filter without sacrificing filtration efficiency.
