K&N automotive replacement air filters are designed to increase horsepower and acceleration while providing exceptional engine protection. This simple to install lifetime air filter is backed by the K&N Million Mile Limited Warranty® and will be the last air filter your vehicle will every need.
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. Since our humble beginnings we 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. We not only have more applications than any other manufacturer of similar product, we invented the High-Flow category and the High-Flow Technology that supports it. K&N also makes thousands of racing and specialty type air filters and is the #1 Filter in NASCAR®.
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. Our automotive OE (original equipment) replacement air filters generally add 1-4 horsepower. The secret to our success lies in the unique characteristics of our air filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. We just wanted to win races and stumbled on a cotton filtration technology destined to be great. Our high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive or motorcycle 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.
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.
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 uses independent laboratories to help ensure that our products meet or exceed your high performance and high filtration demands. Better yet, we conduct our own testing at our own state-of-the-art in-house testing laboratory. For more information on K&N air filters and testing go to the K&N Technical Learning Center area. K&N's dedication to providing a first-class air filter can also be seen outside the testing laboratory. Consider that K&N has sold more than 20 million air filters since 1969. One such filter was put in the airbox of a three-quarter ton Chevy pickup and driven more than one million miles by Carl Judice of New Iberia, Louisiana. Carl points out that he has never rebuilt the engine, nor removed the cylinder head from his trusty pickup truck. Real world testing and customer satisfaction doesn't get any better than that.
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 we encourage you to try our 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 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.
That sounds un-American to us, which is why K&N and the Magnuson-Moss Warranty
protect 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.
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.
We believe K&N makes The World's Best Air Filter and we stand behind that claim 100 percent.
