I'm gunna put some kind of filter on the end of my snorkel when I put my airbox and everything back on my quad. And I was just going to order a replacement for my K&N and then chop up the old one to fit. But I did a little searching and found this on the Outwerwears site: http://outerwears.com/proddetail.asp?prod=4847 I'm wondering if this is a filter that they made specifically for that. I'm gonna have to go get a measurement of the snorkel's diameter, but I'm hoping this is what I think it is. Anybody got any comments? I would do panty hose like some people suggest, but I want it to repel some water also.
