Clean your K&N air filters regularly!!!!
I cleaned my air filter last night and on the way to work this morning i noticed quite a bit of difference in acceleration and overall reaction time of the engine.
Of course, when i took my filter out of the car yesterday I banged it on the ground a few times and was actually able to make a small pile out of the dirt that came off it. I've never seen my air filter that dirty, must be all the dust and crap in the air here in Phoenix. I'll be cleaning it every 6 months from now on. Hopefully my gas milage will improve too.
Just reminding you guys that these filters work great, only when they're clean!!!
now, time to dance...DOMO

I may be wrong but a properly designed filter should filter great from a new condition.
The purpose of an aftermarket filter is to maintain superior flow even as the filter loads up with debris.
The OEM filter will have restriction levels increase exponentially as they load up but a well designed oiled cotton filter will have restriction levels increase only linearly while maintaining a superior filtering efficiency equivalent to OEM paper elements.
The fact that they claim it filters better as it gets dirty is rediculous as that implies it is not filtering so well when new.
Well, guess why? Because its easy to make a filter that either flows well or one that protects well, but to get one that does both well takes some effort.
And the original poster's observation is evidence of that...

The filter should make a nice tight fit with the air box at ambient temps and really seal up as the engine bay gets hot.

You gotta be kidding............?
Where do you guys get your ideas from? A dirty filter doesn't flow more air,
that's one of the reasons we keep them clean. I'm using Stillens CAI which
contains a large K&N filter. I clean this filter every 3K miles and it's never
really dirty at that mileage......but I clean it anyway......more airflow!

I don't think anyone actually said a dirty filter flows better - what was said is that a dirty filter, or somewhat dirty filter, FILTERS better, though a dirty filter will not flow as well, duh.
The context was that smaller particles will get trapped better, when larger particle are in the way. Technically, the air is more filtered and cleaner, when the filter is a little dirty.

it may have less air flow, marginally less (like rick said), but the less air that gets through...the less dirt that gets through as well - theoretically speaking of course.
edit: rick, you beat me to it!
