The Original High-Flow Air Filter

Since 1969 K&N Engineering has been designing, manufacturing, and enhancing High-Flow Air Filters for the automotive and motorcycle enthusiast interested in maximizing horsepower and acceleration. They have designed and manufactured over 2,400 High-Flow Air Filters to fit most modern passenger vehicles and over 500 High-Flow Air Intake Systems to fit vehicles driven by enthusiast minded drivers. K&N also makes thousands of racing and specialty type air filters and is the only air filter used at the Indianapolis 500 Race®.

The K&N FilterCharger® air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. Their automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to K&N’s success lies in the unique characteristics of their filter medium. Their high flow cotton gauze air filter is washable, reusable and built to last for the life of your engine.

K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.

Engine Protection, Filtration

Anyone can flow more air. The trick is to flow more air safely. 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. K&N designs filters with the maximum possible airflow achievable while providing guaranteed engine protection.

The Importance of Oil

A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection. In contrast, most other media can not maintain the same balance of airflow and filtration throughout the filter’s life without sacrificing one or the other. With a K&N Air Filter, there is no sacrifice.

K&N Testing – Laboratory and Real World

K&N uses independent laboratories to help ensure that their products meet or exceed your high performance and high filtration demands. They also conduct their own testing at their state-of-the-art in-house testing laboratory. Consider that K&N has sold more than 20 million air filters since 1969.

Never Replace Your Air Filter Again

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 their testing laboratory, they 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 the K&N filter Recharger® service kit and follow the easy instructions.

K&N Air Filters and Fuel Economy

Fuel economy testing and mileage claims are a tricky business. Just ask the EPA, whose website states, “EPA’s fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA’s fuel economy rating. This is based on a number of factors, such as weather, road conditions, your driving and maintenance habits, and your use of air conditioning.” A lot of exaggerated claims are made in the marketplace by products claiming to improve gas mileage. K&N makes no general fuel economy claims, however they encourage you to try their air filter for yourself. Keeping air filter restriction as low as possible can be an important tool, among others, for maintaining high mileage.

K&N Million Mile Limited Warranty® and Consumer Protection Pledge

K&N warrants its street vehicle OE Replacement Air Filters for one million miles. When used properly and found to be defective, return your filter and the receipt from purchase and K&N will replace it free of charge. K&N’s Consumer Protection Plan goes one step further than its Million Mile Warranty. The performance aftermarket has, at times, been plagued by car manufacturers and automotive dealers that may attempt to discourage you from customizing your vehicle. They prefer you buy OE parts and not modify your car or truck and have even been known to void their own manufacturer’s warranty due to vehicle modification. The Magnuson-Moss Warranty Act protects consumers from such denied warranty claims. When you buy an OE replacement K&N High-Flow Air Filter or High-Flow Air Intake System you can be confident your vehicle’s warranty will remain in effect. If you experience a difficult dealership, K&N will resolve the issue so you won’t have to. The following summarizes the K&N Consumer Protection Pledge:

K&N pledges to our customers that they will not be taken advantage of and charged for a repair due to a dealership warranty denial blamed on the presence of a K&N product..
