K&N FILTERS PROTECT THE ENVIRONMENT

One K&N High-Flow Air Filter™ is designed to last for the entire lifespan of your vehicle. If you assume an engine life of 175,000 miles—and replace your disposable air filter every 15,000 miles—only one K&N air filter will be used during the same period in which eleven disposable paper air filters are discarded. High-Flow Air Filters™ also feature a cotton filtration media; cotton is a renewable, sustainable resource.
