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.

Since installing the air filters I have noticed better gas mileage and a slight increase in power. They were easy to install and come with stickers stating they are lifetime filters so no one replaces them by mistake!
