Never Replace Your Air Filter Again. Handmade in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable. Regardless of what you’ve heard, it’s almost impossible to wash your K&N Air Filter too much. Inside our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification. Depending on your driving conditions, we recommend cleaning your air filter every 50,000 miles.

GET THE MOST OUT OF YOUR CAR OR TRUCK Most people are aware that our 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 air intakes 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 air intake and we sell over 200,000 air intakes every year, so go ahead and wake the sleeping giant in your car.
GUARANTEED HORSEPOWER We will not sell an air intake that does not provide a measured increase in horsepower and torque (acceleration). Our air intakes are proven to increase horsepower and torque on a rear-wheel dynamometer (think treadmill for cars). These thoroughly engineered air intakes provide huge increases in power that a customer will definitely feel when they accelerate.
