Title: K&N air filter
Review: Have used K&N filters for several years. Not only in vehicles but also chainsaws. Very durable, last for years.Never had to replace one. Easy to clean, using the K&N cleaning solution and oil. Don't know if they really help fuel mileage, but it beats having to pay the price of a paper filter once or twice a year.
