K&N Cold Air Intakes are Guaranteed to Increase Horsepower While Protecting Your Engine

 
 
K&N air intake systems are measured and 100% guaranteed to increase horsepower.  We built our first air intake in 1992 and we haven't looked back since.  K&N currently manufactures over 500 different air intakes, commonly referred to as cool or cold air intakes, and our team of engineers is dedicated to designing, and building the best air intakes available.

Restriction in airflow can exist between an air filter and the engine reducing the benefit of our high flow air filter. The weakest link in the "airflow chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N cold air intake systems virtually eliminate air path restriction by replacing the entire air path to the engine with an aerodynamically engineered intake tube that drives a massive amount of air into an engine.

Our cold air intakes are built to increase horsepower. If we can't increase a vehicle's horsepower we won't build a system for it. It is that simple.  Our horsepower results are not based on the single biggest gain from one particular vehicle but are an average of runs and vehicles.  Examples of horsepower gains for several popular vehicles are below.

K&N's cold air intake system 63-2556 was designed for the 2008 Ford F-150 pickup with the 5.4 liter V8 engine.  Our in-house dyno testing shows a gain of 15.47 horsepower @ 3829 rpm with this High Density Polyethylene air intake system.

2004, 2005, 2006 and 2007 Ford F-150 trucks with the 5.4 liter engine use K&N's 57-2556 air intake for a gain of 15.47 horsepower @ 3829 rpm.

Owners of 2004 to 2008 Ford F150 pickups with a 5.4 liter engine may also choose K&N's polished aluminum cold air intake kit 77-2556KP.  The 77-2556KP gets 9.53 more horsepower @ 3725 rpm.

2003, 2004, 2005, 2006 and 2007 Honda Accord models with a 3.0 liter V6 engine use K&N's complete cold air intake part number 69-1207TP or 69-1207TR. These cool air intakes show a gain of 10.4 horsepower @ 5522 rpm.

K&N's cold air intake 63-3058 was engineered for the 2008 Chevy Silverado 1500 truck that has the 6.0 liter V8 engine.  An increase of 17.54 horsepower was revealed when this system tested on K&N's dynamometer (measures power at the rear wheels).

2007 Chevy Silverado 1500 pickups with a 6.0 liter engine gain 17.54 horsepower @ 4917 rpm with the 57-3058 cool air intake. The 57-3058 is designed with a non-metallic rotationally molded intake tube that can reduce intake air temperature and decrease intake sound over a metal tube.


K&N's 77-3058KP will fit 2007 and 2008 Chevy Silverado 1500 models with the 6.0 liter engine. This polished aluminum intake system uses an aluminum intake tube to smooth and straighten air flow to your engine. The 77-3058KP gains 12.49 horsepower @ 4917 rpm.

All K&N cold air intakes begin with "The World's Best Air Filter".  We apply our high-flow technology to a large conical open element air filter, providing more surface area for a huge increase in airflow. The oversize air filter captures and holds more dirt to protect your engine from damage.
