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 currently offer over 500 different part numbers for almost every vehicle application.
BOLT-ON HORSEPOWER GUARANTEED!
	Our 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 sell a system for it.  It’s that simple.  Our 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.
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.
THE WORLD’S FIRST MILLION-MILE LIMITED WARRANTY
	K&N invented the world’s first air filter guaranteed for one million miles. That same warranty applies to our High-Flow Air Intake Systems. Our products are well engineered, built with the finest materials and we stand behind them 100%.
EASY INSTALLATION
Sound complicated? That’s the great part, our 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!  We specifically sell our kits to use existing factory holes and mounting points, making installation simple. The vast majority of our cold air intakes do NOT require any cutting or drilling.
