Air filter/air box

 Hey Chod,
  Don't worry about computor skills and such, The most important thing is getting out ther with the little folks.
I know this sounds cliche' but any one who has raised a few young'ins  know how fast they grow up.  And just as important is the memories they carry of spending time with the Old Man doing what they love.
  Sermon Over :roll:

There is quite alot of theory and science behind the airbox being part of the intake tract, & having the same resonance effect as the exhaust when tuned.   
  I will snoop about a bit and get back with some aftermarket filters if you check back later.
You shouldn't have any problems as long as you keep the seal and filter in good shape.  I have taken in some of the kids bikes around here to "Have a look at" and found the airfilter so mucked up it resembled a giant bran muffin....
  You may also consider a pre-filter or Filter Sock running in the sand.  I have gotten a large pair of womens socks that are actually panty hose type material and streched it over a clean air filter to help with the fine silty/volcanic type stuff we have out here.
  I suffer from hunt and peck single digit typing and the guys here run circles around my engine, suspension and computor knowledge and sill put up with me so your in like flynn!  I had a good spellchecker and somehow goofed that up also.. Oh well.. Live and Learn
Catch you later with some filter options..

I wouldn't eliminate the airbox, the stock design is fine and flows alot of air plus it's kinda good at keeping water out. If you go to a pod style filter you could actually limit airflow because the surface area for air to flow through would actually be smaller.
I'm also not a big fan of k&n style filters on dirt bikes either, the foam filter oiled properly seems to do a better job of keeping dirt out.

i hear this all the time. 900hp TT's and class1's run K&N filter for 1000 mile races with some of the deepest silt in the world with no problem. i have ran a K&N on 3-wheelers, quads, and dirt bikes for 15 + years with no problem. thats in the silt, dust, and sand. in fact the filter to carb boot is cleaner that with the foam. i have had some bad experiences with foam, well with the stock sealing of a foam filter on KTM's. the K&N fixes that and seals up beater than anything out for them. i have also had foam filter pull apart at the seems. the biggest problem with any filter is packing. if the filter is completely packed it will start to pull dirt past it. the K&N tends to pack faster because of the v style of the element. i run a stocking or dust cover and after a 4 day weekend in the sand my filter still looks clean. its not but it looks like it is. the other problem with K&N is people don't do the proper maintenance. cleaning with gas is very bad for one and it open up the gousse letting more get past the filter. the other problem is with oiling them if you dont oil it properly its not going to work., the oil needs time to set too, if you oil a K&N and then go riding the oil will get suck off the filter and into the intake. so IMO a K&N with give you the same level of protection when used right.

Chod:
Thanks for all the info guys,Im going suck it up and keep the Airbox.I really wanted to run the Pod.But with the good advice you guys gave me  :-D its like  Spock says its more Logical. To keep the box. Ill run the K-N  W/Sock.

Friar-Tuck:
 I realize that it can be a pain  getting the filter in and out of the airbox.
     I am by no means an expert or anything, however I think you have made a wise choice,
Live Long and Prosper... :lol:
