The 57 Series Generation II air intake, also referred to as an FIPK®, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with a Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable. Most of our air intake systems are relatively easy to install using tools commonly available.

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
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.
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.
