Horsepower is a measure of the engine’s maximum power while torque measures how quickly you can accelerate. More air entering the engine increases the efficiency of the combustion process creating more horsepower and torque. Simply put, Everything! At its most basic level, an engine is an air pump. As the “look” of a K&N air filter has become popular, many companies have begun offering products that copy that “look.” While imitation is said to be the sincerest form of flattery, K&N own testing has shown that many of these look-alike products do not provide a safe level of engine protection. It is very easy to design an air filter that exhibits high airflow simply by reducing its filtration to unacceptable levels. For this reason a consumer should always evaluate an air filter based on both its filtration efficiency and air flow capabilities. However, you can rest assured that each air filter K&N sell, has been designed to achieve high air flow while providing superior filtration.īoth air flow and dirt protection are critical to engine performance. K&N goal is to design K&N air filters to achieve maximum airflow while targeting overall filtration efficiency at 98%.īecause no two air filters are alike, the specific airflow and overall filtration efficiency will vary depending on the filter in question. This efficiency number represents the percentage of test dust retained by the filter and thereby kept out of an engine. The result of the above test procedure is a specific air filtration efficiency number. As a point of reference, a human hair is approximately 50 microns in diameter. K&N subject a sample of K&N filter designs to this test procedure using Coarse Test Dust, which includes particles ranging in size from less than 5.5 microns to 176 microns.
The ability of an air filter to protect your engine is generally measured using a testing procedure developed by the Society of Automotive Engineers identified as the SAE J726 procedure. We design K&N air filters to provide superior filtration of the contaminants that can harm your engine while maximizing the airflow characteristics of the filter in question. They are seeking the additional horsepower and throttle response needed to win the race.

That is why so many professional racers are willing to run expensive vehicles with no air filter, as opposed to installing a disposable air filter. In the vast majority of cases increased airflow will increase engine performance measured by horsepower and throttle response (torque). The performance benefits of maximum airflow are clear, compelling and well documented. We believe the primary function of an air filter is to deliver both high airflow and superior dirt protection. We design K&N air filters to provide minimum restriction allowing high airflow into an engine.
