We feel a high quality performance intake system is one of the best dollars to horsepower investments you can make and once again K&N is the clearly defined leader. K&N built their first kit in 1992 and haven’t looked back since. They currently manufacture over 500 different part numbers and our team of engineers is designing, building and testing new systems constantly.
BOLT-ON HORSEPOWER GUARANTEED!
K&N systems are built for horsepower. In fact on the 2003 Ford Mustang SVT® we get an impressive estimated 30 horsepower. If K&N can’t increase a car or truck's horsepower they won’t build a system for it. It’s that simple. They establish a stock baseline horsepower with their in house dynamometers and then design our air intakes to get the largest horsepower gain attainable without causing a “Check Engine Light” to come on. K&N's horsepower 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 so we want to ensure repeatable numbers you can count on. In today’s market place there are some pretty big cold air intake claims. K&N doesn’t make claims; they present the facts, backed up by well documented tests.
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 air box is removed we’ve got plenty of room to work with. Now they can apply their High-Flow Technology to a large conical open element air filter, providing more surface area for huge increases in airflow that turn into horsepower you can feel. The oversize air filter also captures and holds more dirt. This increases the service life before a cleaning is required (up to 100,000 miles for air intakes depending on driving conditions).
