But yea, air filter dirt is CRAZY! I washed my Eventuri filter the other day. (I have two and swap between cold/warm seasons. Easier for me to have 2 so my car isn't incapacitated while I wait for the filter to dry.)
Anyway, there wasn't really any dirt on the inside of the filter, but the outside POURED out dirt when I hosed it from the inside. More dirt came out that filter than my wash bucket after not washing my car for an entire month. And that filter was in the car for less than 7 months.

Well, this brings up another timely thread if you're going to run a high ethanol/high boost tune and spend a lot of time at WOT like I do. I'm also guessing this is how the dirt was making it into the oil:

I don't want to turn this into another oil thread, so if you guys have thoughts please post in the thread I linked to above.
Either way, dirt going passed the intake air filter = BAD, so back to OE paper for me.
