Why K&N and not any other brand?
Anyone can flow more air. The trick is to flow more air safely. In our opinion we hit the sweet spot – an optimal blend of high air flow, filtration efficiency, durability and dust capacity. We take filtration seriously. K&N Air Filter media has been tested both in-house and by independent labs using the ISO5011 test developed by the Society of Automotive Engineers. In addition we test many of our filters both in and out of the OE airbox ensuring proper fit and function. Our goal is to design filters with the maximum possible airflow achievable while providing guaranteed engine protection.
Handmade in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable. Regardless of what you’ve heard, it’s almost impossible to wash your K&N Air Filter too much. Inside our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification. Depending on your driving conditions, we recommend cleaning your air filter every 50,000 miles. To clean and re-oil, purchase our filter Recharger® service kit and follow the easy instructions.
K&N also offers a Million Mile Limited Warranty and Consumer Protection Pledge. Their filter are often imitated, but their competitors has not stand out to offer this.
Many models available for all CC bikes

A filter, unlike a complete bike, is only so small. There is not much to differentiate itself from another. Thus, imitators and competitors can only try to differentiate themselves from K&N by using different materials and other negligible features.
Please think about it, if your air filter frame is made of some exotic high-end material (which you pay for in the air filter price), and yet your OEM air box is made of ABS plastic (which is nothing wrong in the first place), would the air box and air filter expand differently under heat? If yes, would this affect sealing?
Are you paying a premium price thinking you get a better product or are you supplementing ad costs and high margins to bike shops so that they will be financially motivated to convince you that it is a better product?
Thankfully, K&N being the pioneer and original Hi-flow air filter manufacturer (Consider that K&N has sold more than 20 million air filters since 1969), is able to obtain economies of scale in their manufacturing and pass on additional value and cost savings to the consumer. You get exactly or even more than what you pay for.
Air filters are not measured by micron size. As an industry standard, air filters are tested in accordance with the ISO 5011 test protocol to measure capacity (the physical amount of dust a filter can hold before cleaning is necessary) and efficiency (the filter's ability to trap and hold dust). See technical service bulletin 89-5R from the Filter Manufacturer's Council. The dust selected for the test contains a specified distribution of different particle sizes according to ISO standards.
The content of the two most commonly used types of ISO test dust for air filters is as follows:
ISO COARSE TEST DUST ISO FINE TEST DUST
Particle Size in Micrometers (Microns) Percent by Volume
Particle Size in Micrometers (Microns)
Percent by Volume
001 - 005

10 - 20
020 - 040

040 - 120

120 - 180
As has become customary in the automotive industry, we use Coarse Test Dust for gasoline engine air filters and Fine Test Dust for diesel engine air filters. This practice of using different grades of test dust developed because Diesel engines require higher levels of filtration because they operate at much higher compression and require tighter tolerances than Gasoline engines.
Our testing has demonstrated that on average, K&N replacement air filters and air intake systems have a cumulative or Full Life filtration efficiency of between 96 and 99%. Different filters test at different efficiencies due to changes in their shape, surface area and relationship to the direction of air flow through the factory air box or test housing. Like most air filters available in the USA, our filters will provide all the engine protection you need.
