Joe Sou, Buena Park, California
I've been using K and N air filters in all my cars. It gives the performance I wanted and being re useable is a must. Lasts up to 50,000 miles before needing to be cleaned. I highly recommend.
Marvin Cross, Redondo Beach, California
I bought replacement air filters for my newly purchased 2011 Mercedes E350. After 200 miles of freeway driving with the stock filters I got 27mpg. With the K&N filters installed and after another 150 miles, I got 29.5mpg and the car feels more responsive at the low end. These are great filters, period.

Have been a K&N user for 40 years and use their products in both my street cars and my race cars. Simple, guaranteed to fit right and economical since they are cleanable and resuable. Can always count on them for some extra fuel milage gains too once the ECU has time to update itself.
