IMO, both are basically equal, with the Amsoil being the preferred brand, tho I can't explain why. I believe the K&N is recommened for more-frequent recharges. I really like my Amsoil and would recommend it highly. My review is here.

A search of "Amsoil" and "K&N" in this forum should yield more info than you need. Don't spend much time on it, it's just a drop-in air filter.

I've used both (but not in the same cars). It isn't going to make a lot of difference really...both are good. Like LordBass said one isn't going to be that much more effective vs the other...so I'd get the one you can get the cheapest.

amsoil needs to be cleaned and reoiled once a year or every 25000 miles, which reminds me.

k&n needs "recharging" every 10k i believe.

The amsoil made a huge difference in my wifes car (02 Sentra SE-R). I like the fact you need to recharge it way less, and the filter seems more durable in general.

Default question

I just installed an Amsoil and was told that it would get clogged really quick, since I usually drive in really dusty conditions... the person said that if you were to stretch out a paper filter and compare that surface area to the "random" pores in the spunge-like Amsoil, the K&N and stock filters would be superior. Sounds like a fair argument, but my stocker was caked black to the point where I could hear and feel the engine choking after just 8K miles. Anyway, he never specifically researched air filtration either. I change my oil every 2K, so I guess I might have to clean the Amsoil as well. We'll find out. I say, go with what is more convienient for you.
By the way, beware of the small metal chips that are in the perforated sheet in the Amsoil. I found two on mine. Its dangerous since the metal side faces the throttle body.

Actually the amsoil filters better than K&N, and goes longer between charges...

The oiled foam Amsoil filter actually performs well in dirty dusty conditions, and the more dirt it collects the better it filters dirt while still flowing well.

This is because while the holes in the foam are larger, the filter is deeper with more total potential dirt-collecting surface area, yet flow doesn't suffer when it collects dirt because of the size of the holes.

A good foam filter will almost always be better than a K&N, and Amsoil makes a terrific product. I have seen a few cars equipped with K&N filters with gunk starting to build up in the intake... I have yet to see that with an Amsoil but to be fair I have also seen a lot less cars with the Amsoil.
