These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.

Get the most out of your car, truck or SUV with a K and N Cold Air Intake System! Most people are aware that a 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 is why K & N Cold Air Intakes rule the road! K&N Cold Air Intake Systems replace the factory airflow assembly including the filter, air box and air path. More people are discovering the monster power available from a well-engineered Cold Air Intake System. K&N sells over 200,000  Cold Air Intake Systems every year, so go ahead and wake the sleeping giant in your car.
