Most people are aware that K&N 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 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, so go ahead and wake the sleeping giant in your car.
