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) ![]() ![]() ![]() |

Just eyeballing the things doesn't prove how well they work or don't work. Do you have some way of measuring the amount of particulate each one catches in a controlled environment?

There are plenty of studies out there. To pass the same amount of air through a smaller area, the restriction has to be reduced. Fewer square inches of media, larger passages through that media. To increase the amount of air passing through, you have to increase those holes to an even larger size. In this case, you can SEE through the filter media. That means relatively BIG stuff can get past it. The Cap'n |

I used to wipe fine sand like stuff out of my intake pipe on my K&N 'filtered' GTI. Every car that I have worked on that had a K&N had dirt on the throttle body. My old Mustang had one and has pretty serious cylinder wall wear at 25,000 miles (I had it apart when I wiped a few the rod bearings when the oil pump drive snapped.)
