"Though the initial price is high, you're getting a high quality filter that can be easily cleaned and used again. I have used K&N filters on my motorcycles for years and am very happy with their performance. I live in a desert area with lots of dust and other particles in the air. In my opinion a paper filter is just not going to do the job over the long term. I know the K&N's will do the job." —John K from Las Vegas, NV bought a K&N Air Filters for a 1999 Mercedes-Benz SL-Class.
