Increased Horsepower, Torque, & Gas Mileage


BOLT-ON HORSEPOWER GUARANTEED!
K&N intake systems are built for horsepower. In fact on the 2003 Ford Mustang SVT® their intake can get an impressive 30 horsepower. K&N establishes a stock baseline horsepower with their in house dynamometers and then designs the air intakes to get the largest horsepower gain attainable without causing a “Check Engine Light” to come on through multiply repeatable runs.
 
HIGH-FLOW TECHNOLOGY
How do they increase horsepower so consistently? It all starts with The World’s Best Air Filter. Even a K&N replacement air filter is limited by the size of the original air box but once the the air box is remove, their is more room to design a system with less air flow restriction. This allows for the use of a large conical open element air filter, providing more surface area for huge increases in airflow. The oversize air filter also captures and holds more dirt with less restriction to air flow. This also increases the service life before a cleaning is required.
 
AIR INTAKE TUBES
Improving the air path between the air filter and the motor is the next big area of improvement. K&N offers two options for many air intake applications. Part numbers starting with 57 or 63 (except Gen 1 and 57i Series) incorporate molded High Density Polyethylene tubes that are black in color. Part numbers starting in 69 or 77 have aluminum tubes and are polished, powder coated or anodized. The molded Polyethylene systems offer the most flexibility in air intake design and the best possible horsepower numbers. The aluminum intake systems offer power with a more stylish look.
   
50 STATE STREET LEGAL

Many K&N 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 kit 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. 
   
EASY INSTALLATION
K&N Engineering's air intake systems are easy to install.  A typical installation can be done with a screwdriver, pliers and a ratchet-set in 90 minutes or less!  K&N specifically engineer the kits to use existing factory holes and mounting points, making installation simple. The vast majority of their air intakes do NOT require any cutting or drilling.
