K&N Limits The Duration And Remedies Of All Implied Warranties, Including, Without Limitation, The Warranties Of Merchantability And Fitness For A Particular Purpose To The Duration Of This Express Limited Warranty. This Limited Warranty Gives You Specific Legal Rights And You May Also Have Other Rights, Which Vary From State To State. K&N® 10-Year/ Million Mile Limited Warranty The company actively promotes the environmental, economical and performance advantages of long-life reusable cotton gauze filters. K&N is the sales and brand leader for performance filters, including an extensive line of factory replacement filters and performance air intake kits. The first K&N was conceived for racing over 50 years ago and a performance enthusiast mindset continues today throughout all levels of the company. K&N® is the inventor and leading innovator of reusable cotton gauze filter technology for automotive applications. It can be washed and reused many times, and since you can usually drive up to 50,000 miles between servicing, you won't have to clean it very often. The K&N filter is economical because it's the last air filter you'll have to buy for your car.
Contrast this with a paper filter that only traps dirt on its surface as the surface area becomes clogged, the airflow rate goes down.Įach K&N air filter is custom designed to fit into your existing factory air box. The thickness of the layers also allows the K&N filter to trap dirt and dust on many levels, trapping more dirt without decreasing airflow. The layers of oiled cotton fibers in the K&N filter trap dirt particles that are smaller than the holes in the filter media. The resulting K&N filter not only delivers increased airflow while trapping dirt particles that could harm your engine, that level of airflow is maintained even as the filter gets dirty. The cotton is then treated with a specially formulated grade of oil that causes tackiness throughout the cotton's microscopic strands. K&N's solution was a filter design consisting of 4 to 6 layers of cotton gauze sandwiched between two aluminum wire screens. But just increasing airflow without ensuring adequate filtration under those conditions would result in a ruined engine. Increased airflow improves the efficiency of the combustion process, increasing horsepower and torque. K&N's initial goal was to develop a filter that would deliver increased airflow during dirty, dusty off-road racing conditions. The secret is in the K&N filter's construction. K&N air filters increase airflow without decreasing filtration ability, and the increased airflow remains consistent throughout the filter's service interval. And airflow decreases as these air filters become dirty. OEM filters, which are usually made of paper, filter adequately but at the expense of airflow. Many high-performance filters deliver better airflow, but sacrifice filtering ability and engine protection in the process. Most air filters on the market are a compromise.
