HIGH-FLOW AIR INTAKE SYSTEMS SINCE 1992 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. We built our first kit in 1992 and haven’t looked back since. We currently manufacture over 500 different part numbers and our K&N team of engineers is designing, building and testing new systems constantly. BOLT-ON HORSEPOWER GUARANTEED!K&N Performance Air Intake K&N systems are built for horsepower. In fact on the 2003 Ford Mustang SVT® we get an impressive 30 horsepower. If we can’t increase a car or truck'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 design our K&N air intakes to get the largest horsepower gain attainable without causing a “Check Engine Light” to come on. K&N 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. We don’t make claims; we present the facts, backed up by well documented tests.
