Dry Washable air filters?

that looks similar to other cotton/gauze and oil filters. On a stock vehicle no real need. For performance they flow more air but trap less fine dirt than a good fibrous or paper filter. I have similar cone shaped K&N on my 2002 F150 with 180K it still runs like a top. no damage from dust getting thru and just clean the filter when it gets gunky.

Go with AEM DryFlow instead. They have independent lab test to show filtration efficiency and flow, etc., as compared to oiled K&N's etc. Here is the test by Southwest Research Institute as a PDF:

Thank you so much. I also see the aem is the same price here (in Canada,) as the OEM paper filter.

Yes they let more pass through in 2 ways dirt and air a paper filter will flow more than enough air and filter way better

I've had great results with aFe Pro Dry S filters. On my previous vehicle, it was the only filter that kept ppm of silicon to single digits on my used oil analysis. I believe AEM or aFe Pro Dry S would be your best options.
I haven't used AEM, but their reputation is good. However, they didn't offer a drop-in replacement for either of my cars. So, for a stock air intake replacement filter aFe was my choice. Both aFe filters I've used were very well built. Thick, sturdy filter gasket, and high-quality synthetic media that is easily durable to the light washing required to 'clean'.
However, I doubt I'll need to remove the air filter for a couple years at least.

Yes, a filter of any type is more efficient with a thin layer of debris on the filter. The flow may reduced a little but still much more than needed.
This is even more true of oiled washable filters as they literally need the oil in order to trap more dirt to begin to accumulate contaminants to the point efficiency isn't as risky.
This is another reason I prefer the dry washable as how long will it take to get a small layer going to up it's efficiency and still yield a higher air flow with essentially as good filtration protection as paper filters.
To me, it's the best of both worlds. Filtration comparable to paper filters (arguably the same after in use for a while) and less risky compared to oiled ones. Win/win as long as you aren't in a really dusty environment. IMO.

A question about the AEM - can it be cleaned with Simple green?
