Ok there was alot of talk about me getting sand and other debris in to my intake. Since the mod I drove about 1.5k miles, i also live next to a construction site with lots of sand on the road.
What I found when I opened the airbox:
Filter was really clean there was NO SAND OR ROCKS.
A part from the small leaf and 2 small bugs. there was nothing there.
After rinsing with water in to a white bucket (gold rush style) i found nothing: no micro sized sand.
In Conclusion: I believe this is a safe way to mod the air box, to get the same or even better results as an evo kit or carbonio kit<ul><li><a href="http://forums.audiworld.com/performance/msgs/68695.phtml">original post</a></li></ul>

Why didnt you run a air-tight tube from the airbox to the grill? That way when you are not going 70mph+, you can still get some relative cool air.

something lest he lead more than you down this path.
The fact that he didn't find any grit on the filter media or in the air box is because it passed through the filter into the intake path and engine, there to do its damage. The oil type filters MUST have the specified oil on the media for them to trap dirt and detrious. By stripping his K&N of the oil his filtration is only marginally better than if he had pulled the filter media entirely.
There is a reason filters are in the intake path to begin with. It is to trap fine particles before they get into the engine. Pulling the oil will result in shortened life for both his engine and more than likely his turbo.

filtration, your failure to acknowledge many (especially automotive engineers) know much more than you or keep your head in the sand and deny it had anything to do with your fvck up.

then vacuum up a pile of dust and dirt. What happens to that pile? Is it in the tank or did it travel thru the tank and out the discharge port? Your air box is the tank and your engine is the discharge port.

like most of the retards here who are too stupid to blames themselves for the stupid things they did to their own cars.

so if oiled k&n removed 99% of them, since my is not oiled ill give it 70% removal rate, so the math is : STFu
You only have to oil it/clean it once a year *at most*.
Your engine isn't going to blow up in 10k miles since your oil filter can trap a lot of the smaller particles and you're not feeding in a bag of sand, but over time you will damage the engine or the turbo.

Like I said, your engine won't explode, but there's a reason engineers spend their time worrying about those extremely tiny particles when they're thinking about how to filter the air and oil properly. If it isn't worth it to you, I wish you the best of luck with it.
To answer your question: I have used K&N and other brands of aftermarket filters, but I have always oiled them, so I can't personally attest to the results of running them without oil.

I'm not willing to try it because of a lack of first hand experience.
Filtration of harmful particles is science not hearsay. There is not only a specific SAE test procedure (Society of Automotive Engineers Test Code J726) for testing filter media there is a commercially available test 'dirt' for running this test.
The OEM paper filter relies on holes smaller than the size 'dirt' particle that has been tested to show damage to a car engine. The downside is that the tiny holes tend to not flow air all that easily, especially as the holes get plugged by 'filtered' debris. An oiled foam or oiled cloth (K&N) filter relies on a coating of sticky oil to trap these particles as without the oil the media's holes are too large to stop the smaller harmful particles.
Now if you wish to disregard all the science behind air filtration that is certainly your perogative. However, it is our perogative to caution those who might be inclined to follow your folly.

This is the kind of simpleton that when you warn him he's sitting on the wrong side of the tree branch he's cutting off, he gets mad at you. Then when he crashes to the ground he blames you for not warning him. Let him burn - he needs to.

Or get a hold of an old JC Whitney catalog. You need minimal intelligence to learn from other people's mistakes but at least some common sense to avoid being played the fool.
