GET THE MOST OUT OF YOUR CAR OR TRUCK
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 K & N's 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 K & N intake kit and we sell over 200,000 K & N intake kits every year, so go ahead and wake the sleeping giant in your car.

GUARANTEED HORSEPOWER
K & N will not sell an intake kit that does not provide a measured increase in horsepower and torque (acceleration).  Each K & N 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.
