K&N Air Filters are handmade in the USA and in the United Kingdom using only the finest materials. A K&N Air Filter consists of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. This design allows for superior filtration of the contaminants that can harm your engine while maximizing the airflow. The more air entering the engine increases the efficiency of the combustion process creating more horsepower and torque. Horsepower is a measure of the engine's maximum power while torque measures how quickly you can accelerate.
K&N Air Filters are washable and reusable. Depending on your driving conditions, K&N recommends cleaning your air filter every 50,000 miles. To clean and re-oil, simply purchase a K&N filter Care Service Kit and follow the easy instructions. Because K&N Air Filters are washable and reusable, it will last the life of your vehicle's engine. If you assume an engine life of 150,000 miles in which a disposable air filter must be replaced every 15,000 miles, only one K&N air filter would be used during the same period in which 10 disposable air filters were discarded. Not only it saves you money and eliminates them from our landfills.
