The "authority" on air filters speaks:
I was watching Alias last night, the episode was "Passage"
A team comprised of Irina, Sydney, and Jack (Irina and Jack are sydney's parents) are in India trying to retrieve the plutonium cores. Anyhow, one of their contacts in India has a truck for them to use. irina (played by Lena Olin), asks him - "what kind of air filter does it have?" THe contact replies, "a foam filter"
Lena Olin gives this nasty look, "that won't do!! It'll clog up before we reach our destination!"
She gets into an Argument with Jack and eventually they take off w/ the foam-filter equipped truck. 10 miles before they reach their drop point, the truck stalls out.
So the writers of Alias say, foam filters are bad for dusty conditions! LOL
BTW if I remember correctly, the race cars used in the desert races do use K&N filters. If you used foam filters for anything they'd clog up real fast. My HEPA filter at home uses a foam pre-filter for the paper panel filter and the foam clogs up in 3 months and was designed to be thrown out.
I use foam filters for my PC air intake and they clog within a few weeks.
The whole point of a K&N is that it won't clog to a point where hardly any air gets through. The entire filter can flow 800+ cfm (doesn't mean you get +5-15hp) so if the center part or any major part is totally 100% clogged, the sides can still flow an adequate amount of air.
From every K&N/cotton-gauze users experience, no normally aspirated application has had an engine failure using K&N. I've heard ppl put about 100,000 miles on their engine using a K&N and its still running hard. I'm sure Amsoil foam filters will be more than adequate for street use. They market their products very well and have a very good customer support base.
