The exact function of an air filter is to provide high flow of air with minimum resistance and to filter the air coming in. The filtering is done to protect the machinery from the dirt from the outside world. Sometimes you may have seen racers racing with their air filters open, this is to provide high flow of air. This habit in the long run will ruin the engine. Their air filters are measured in accordance with the testing procedure ISO 5011. The degree of success of this test represents the amount of dust not allowed to enter the engine and it showed an excellent figure of 98%. A paper air filter work in a go or no go manner that’s why paper filters are so resistive in nature. There are different scientific laws that determine how the dirt particles form the airstream which are interception, impaction and diffusion. In a paper filter the dust particles is mostly found on the surface of the media. But in K&N air filter we have depth loading, multiple levels of cotton fibers show different degrees of dust retention. The cotton fibers is sandwiched between pleated aluminum screen which further increases the surface area .Dust particles caught on the surface of K&N filter have less effect on the air flow comparing to paper filter.
The advantages of using K&N air filters are
- Excellent filtration and high air flow.
- Washable and reusable
- Increase in acceleration horse power and acceleration.(depending if mileage filter or power filter is used)
- It will not void warranty
- Last up to 50000 km before cleaning.
