I installed (2) required air filters on my Mercedes-Benz SL500 and instantly noticed my average Highway milage go from 22 mpg to 25mpg astounding! Horsepower may be increased but hard to tell since car starts with 302hp more than adequate to move it down the road.

Helps MPG & the environment! Just think you clean it & re-use it! no filters in the landfill! Just make sure to save your old filter to put back in while your cleaning this one! It's wouldn't be to great if you put the wet filter back in the car!

Great quality air filter and easy to install. Looking forward to having it in use for the life of the car. Great price too, as I went to Autozone and while they didn't carry this model of K&N filter, those they did have were more expensive than that what I got here.

Just be sure to put it in right. Clean out area is needed. It works great and got 2 MPG better in my A4 Audi and seemed to be a little quicker.
