Air filter socks?
 

I remember seeing in a forum if i'm not mistaken some kind of sock(cloth) that would go over the existing 1/8th off road air filter and work like a three stage filter.
This is without oil and will keep most of the dust out.
Anyone knows the site or a shop that i can purchase these?

yup they are called outerwears. go to outerwears.com.

Doesn't it affect the foam filters or the oil on them in any way?

The Outerwears work well...no effect on foam/oil etc. www.tkocompetitiondev.com is a dealer/dist. Filters in stock.

Nice site, i just ordered one from there, Great price on shipping as well.

any plans to make jammin cr carbon arm guards??

Thanks
Alan

These things work well if you have a real dusty track. I've seen guys using the dust bags from little had vacums as well. Looks kinda funky but it works.
