Here are some comparison photos and a little math for your viewing pleasure. I might mention that you can SEE THROUGH the K&N, down in the folds.
This particular part fits a 2003 MB C320 Kompressor coupe. The K&N has 128 square inches of filter media, the Mann has 1752 square inches! That's over THIRTEEN TIMES the filtering area! Attached image(s)

I searched the web a little and couldn't find the article, but there was a mining company that used a lot of air filters on thier heavy equipment, so some of the engineering guys (who are also car guys) wanted to try K & N's to see if they saved money and protected the engines better.
The article stated the K & N's were much worse on the engines than a high quality paper filter. Too bad I couldn't find the article. |

I have that bookmarked somewhere and will post it when I find it. The author was very biased toward the K&N and probably would have got a big fat bonus if he could show that a K&N type filter would work and save the company money (lots of money in this case.) The tests were a total bust that showed the K&N filters did not actually filter and let lots of dirt into the engines - not real good in a mining environment.
