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. 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 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. 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 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.
Engine Protection, Filtration
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. Click here for
more information on Carl and his million mile truck.
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 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.
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.” Under Gas Mileage Tips they go
on to say, “Replacing a clogged air filter can significantly improve your
car’s mileage”. 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 Act
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. The following summarizes the K&N Consumer Protection Pledge:
K and N Filters 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 Intake Air Filter and engine oil filters which we stand behind that
claim 100 percent.
Each K&N oil filter features a unique hex bottom that allows the filter to be easily removed with a wrench or socket.
