Of course, all that would do is require more frequent filter change. It wouldn't allow more dirt into engine. It would just allow less air as filter clogged.
So his question is a little invalid.
What is valid is a filter that allowed more particles past it than stock, would have what result? Wouldn't those tiny particles 'atomize'? The answer is, no. Not at all. But the worry isn't they will get into the oil, and cause bearing wear. The worry is they will get on the cylinder walls, and cause ring and cylinder wear. Lowering compression over time, more oil blowby, loss of power, early engine demise.
The cylinder walls have a light coat of oil, so any grit that gets to cylinder, will tend to stick to the cylinder walls. Yeah, some of it will shoot out the exhaust not causing damage, but some of it will stick to cylinder walls, and when piston slides back through it on next stroke, it will act like sandpaper, grinding away at walls and rings.
For those who don't know whats in a UOA

I change my filter at the start of winter because there is less dust in the air(rain does a very good job of cleanning the air) that way my filter gets the larger stuff first and that helps when the fine dust hits the filter.
One more thing, If I had FI this gauge would be one of the first things I'd put on the intake. Don't want to spend all that money for FI and then maybe put a restiction on it to cost me some HP.

One more thing, I hope no one on here uses compressed air to blow out the filter before cleaning. Thats a sure fire way to kill your engine.
Here is just one of many sites that will show you how much dirt a filter damaged by compressed air will let in.

I could have covered some of the filter with plastic wrap to see how much it would take to get a restriction. When I get some time I think I'll experiment a little to see how much one would have to block off to get a restriction from the filter. Thats the nice thing about being retired, having time to play with your toys.

This is an interesting thread. I think I'm going to stop changing out my air filters so much. Every time I read intake threads I end up concluding that I'm sticking with OEM. I like that intake noise as much as the next guy, but I'm honestly not trying to attract attention out there.

My all time favourite intake is the Mugen. While I'm not a fan of cotton gauze filters, I ran a K&N drycharger type fabric cover over the Mugen cotton gauze filter to prescreen sand and dust , it worked great and didn't affect performance at all.

Most aftermarket intakes sound obnoxious to me in the VTEC range, buzzsaw is the best way I can describe it.
