Works well
Fit like a glove in the C300 and improved the horsepower, not by a lot but any improvement is better than nothing, also made the car sound better.

Increased fuel economy by 5%
Easy to install. As best as I could measure, it increased my fuel economy by about 5%. No noticeable change in performance. As is any air filter, it was easy to install. K&N filters are not cheap so I am unsure of the long-term value.

The Last Air Filter You Will Ever Buy...
You can install a K&N Air Filter and almost forget it. If you're like me and live in a city you may never have to clean the filter again. Every five years or so, anyways. If you live in a rural or dusty location you can definitely get more life from your engines and equipment as these filters work better the dirtier they get.
