K&N Takes Air Filters Seriously - For over 30 years K&N manufactured serious air filters completely unlike traditional disposable filters. Their air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. The secret to K&N's success lies in the unique characteristics of our filter medium that was originally developed by K&N all those years ago in the dust, sweat and tears of desert motocross racing. They just wanted to win races and stumbled on a cotton filtration technology destined to be great. K&N's high flow cotton gauze air filter is washable, reusable and built to last for the life of an automotive engine. The filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.

Most of K&N High-Flow Intake Kits can be purchased for less than $350.  On the 2003 Ford Mustang SVT^®, they have actually achieved a 30 horsepower increase.  Even K&N's typical kit gains are in the range of 8 to 16 horsepower.  To send an average V-8 down the road at 55 mph, it takes about 17 horsepower.  Considering this, you begin to realize just how much of a difference K&N's kits can make when you step on the gas.  They're proud of these kits because after you bolt one on, you’ll know something’s different…VERY DIFFERENT!

Most people are aware that K&N's High-Flow Air Filter can increase horsepower over a traditional disposable air filter.  An air filter change alone however, cannot eliminate other types of air restriction built into the vehicle at the factory.  These can be found in the size of the air box and the air path running from the air box to the engine. That’s where intake kits rule the road.  They completely replace the factory airflow assembly including the filter, air box and air path.  More and more people are discovering the monster power available from a well-engineered intake kit and we sell over 200,000 intake kits every year, so go ahead and wake the sleeping giant in your car.

K&N will not sell an intake kit that does not provide a measured increase in horsepower and torque (acceleration).  Each kit is proven to increase horsepower and torque on a rear-wheel dynamometer (think treadmill for cars). These thoroughly engineered kits provide huge increases in power that a customer will definitely feel when they accelerate.
