Cold Air Intakes

K&N FIPK Offers Bolt-on Horsepower Guaranteed!
The K&N FIPK cold air intakes are built for Horsepower and added diesel performance. If K&N can't increase a vehicle's horsepower they won't build a system for it, it's that simple. K&N establishs a stock baseline horsepower with thier in-house dynamometers and then work to get the largest horsepower gain attainable. The K&N performance 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.

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.

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.

It's a cinch. K&N packs the FIPK with a complete hardware kit and detailed step-by-step instructions to get the job done in less than an hour and a half. It even mounts to factory locations—no modifications or drilling. And, K&N protects your FIPK Air Intake Kit with a 10-year/1,000,000-mile warranty. Order now, and feel the FIPK difference everywhere you drive.
