Looks like this:

K&N makes all kinds of equipment but that's their 'classic'
style.

If I read your links right, it is a combination of things - mainly a
filter gets better in early part of usage from the bigger holes getting
blocked by dirt, and every time you mess with your filter, you run the
risk of accumulations of dust/dirt falling into the ducting downstream
of the filter barrier point.

I work in a mining area, and there's a 3/4 mile of dirt/gravel road I
travel into and out of my office every week day. Not nearly what
agricultural dust is like during your various plowing and harvesting
operations, but I do have to change air filter way more often than the
typical motorist.

I was getting ready to post a link to the Spicer air filter study, but
all the links I have appear to be inactive. Anybody have a working link
for that?

For reference, here are a couple of links that used to work in the past:
http://www.duramax-diesel.com/spicer/index.htm
http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm

These links, in which the guy who did the study tells about interaction
with K&N over the study, are still good:

The OP claims that all passenger cars will run fine using a 10,000
mile oil change interval.

Your research indicates that both Toyota and Mopar techs consider that
to be bad advice since 10,000 miles is LONG past their normal
maintenance schedule.

Perhaps the OP should go back and reconsider the test before he goes
off half-cocked again. On the other hand, the OP really believes that
all accumulated observations are worthless compared with a
quantitative result from a single, poorly designed test. Well, all
observations other than his own.
