K&N Diesel Air Intake Systems and Replacement Air Filters
Using filtration technology developed and refined over the last 40 years, K&N Diesel air filters provide the protection you need and the performance you want.
Based on a foundation of 6 layers of oiled cotton gauze sandwiched
between two epoxy coated metal screens, K&N air filters for diesel
trucks provide increased performance, protection and a lifetime air filter that never needs to be replaced. Adding diesel performance has never been easier.
Diesel Performance - Horsepower and Acceleration
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. Our OE replacement
air filters generally add 1-4 horsepower, and the large performance filters on our
diesel air intake
systems help provide an increase of as much as 22 horsepower. We have 5 in-house dynamometers that we use to test our air filters and
air intake systems enabling us to verify horsepower gains. Be assured, K&N will not release a diesel
air intake system without a verifiable and repeatable increase in horsepower.

K&N DIESEL AIR INTAKE SYSTEMS
Bolt-on Horsepower Guaranteed!
Our systems are built for Horsepower and added diesel performance. If we can’t increase a vehicle’s horsepower we won’t build a system for it, it’s that simple. We establish a stock baseline horsepower with our in-house dynamometers and then work to get the largest horsepower gain attainable. Our numbers are not based on the single biggest gain from one particular vehicle but are an average of runs and vehicles. Many times an identical vehicle will perform differently and we want to ensure repeatable numbers you can count on. In today’s market place there are some pretty big claims.
We don’t make claims; we present the facts, backed up by well documented
tests. Find horsepower gains of diesel air intakes for your vehicle using our
product search.
High-Flow Technology
How do we increase horsepower so consistently? You might have guessed it starts with The World’s Best Air Filter. Even a K&N OE replacement air filter is limited by the size of the original air box. Remove the air box and we’ve got plenty of room to work with. Now we can apply our High-Flow Filter Technology to a large conical open element filter, providing more surface area and as much air as a normally aspirated diesel engine can breathe. The oversize air filter also captures and holds more dirt increasing the service life before a cleaning is required (up to 100,000 miles depending on driving conditions).
Diesel Air Intake Tubes
Improving the air path between the filter and the motor is the next area of improvement. Our Diesel application High-Flow Intake Systems incorporate rotationally molded High Density Polyethylene tubes and are black in color. Our molded Polyethylene systems offer us the most flexibility in design and the best possible horsepower numbers for added diesel performance.
50 STATE STREET LEGAL
Many K&N Air Intake Systems are street legal in all 50 states and include a California Air Resource Board (CARB) Executive Order (EO) number that ensures the kit has been tested to comply with emissions standards. EO
numbers apply to the intake as well as the year, make and model it is being installed on. Systems with no EO number are street legal in most states but may not be used on emissions controlled vehicles in the state of California. |

The 2003 - 2007 Powerstroke presented a unique challenge, with a cartridge style OE
air filter that’s both expensive and difficult to replace. Our engineers built an entire new air box with a deep oval filter
that flows more air and provides an increase in power (part
number E-0780).
The 2006 - 2010 Duramax air filter (part number E-0781) required a strong metal cage.
We achieved higher air flow and more power over the OE air filter.
The 2007 and 2009 6.7L Cummins gain a lifetime of diesel performance with K&N's high-flow air filter (part number E-0784).
The 2003 - 2007 5.9L Cummins air filter (part number E-0776) is a good example of our design capabilities. By utilizing the entire depth of the OE air box we replace the flat
OE panel filter with a cube style filter flowing significantly more air and providing
extra power.
The Original High Flow Air Filter
Since 1969 we have designed and manufactured over 2,400 High-Flow Air Filters to fit most modern passenger vehicles and over 500 High-Flow Intake Systems to fit vehicles driven by enthusiast minded drivers including
diesel trucks. 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
which were recently used to win the 2007 Baja 500 & Baja 1000 and the 2009 Daytona 500.
Diesel Engine Protection, Filtration, and 6 Layers of Cotton Gauze
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
air filters with the maximum possible airflow achievable while providing
outstanding engine protection. K&N diesel air filters are made with 6 layers of cotton gauze and are built to withstand the higher volume of airflow generated by
diesel motors.
The Importance of Oil
The K&N air filters made for diesel trucks are made of 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
it 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.
Testing - Laboratory and Real World. Over 500,000 diesel filters sold!
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. 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, over 500,000 of them specifically for diesels. One such
air filter was put in the airbox of a three-quarter ton gasoline powered 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. For more info on Carl click here.
Never Replace Your Air Filter Again
Handmade in the USA using only the finest materials, K&N O/E replacement and
intake 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
Oem replacement air filter every 50,000 miles. To clean and re-oil, purchase our filter Recharger® maintenance kit and follow the easy instructions. |

THE WORLD’S FIRST MILLION-MILE WARRANTY
K&N invented the world’s first air filter guaranteed for one million miles. That same warranty applies to our
high-flow air intake systems. Our products are well engineered, built with the finest materials and we stand behind them 100%.
K&N Million Mile Limited Warranty® and Consumer Protection Pledge
K&N warrants its 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 O/E 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. [READ MORE] |
