I've been out riding in the powder twice the last couple days, and both times when I got done the foam on top of the airbox was completely covered in ice and snow, to the point that the foam was starting to get pulled into the box farther due to suction I'm guessing. The foam gets completely plugged. The sled wouldn't reach peak rpms toward the end either, no doubt because of the air intake restriction. Is this common? I've never noticed it this bad before, and I don't like it...had to cut my ride short...the foam is sitting in front of the corn furnace right now drying out. Any way to help stop this from happening?
i belive they make a sock to go over them i have seen a few sleds with them

I cant remember where I saw em, but someone was making inserts for the intakes below the windshields. They would be flush with the outside of the opening and go back in about 4", and were made of some sort of foam. I'll do some looking around to see if I can find them anymore.

SLP flo-rites will mount in the dash and give you a good cold air intake if you want it. Better watch your jetting if you put these in, they will lean you out.
They will not keep snow, which then turns to water, from gathering on your air box. About all you can do is buy a pre-filter that fits over your air box, it will keep a lot more water from going through your air filter. I've wondered about buying pre-filter material and covering the hood screens with it, should work pretty good. They would keep snow out of the engine compartment, but you had better clean them off once in a while or the under hood temps could cause problems like melting your hood, etc.

Outerwear Racing(yahoo or goggle it) out of MI makes them for the Viper, they run right around $20-$25. I ran 1 on my Viper when I had it and it did what it was supposed to.
I think I'll have to get the prefilter. I looked at SLP's site and all I could find were Mountain Max prefilters, nothing made for a viper. They also have universal cut-to-fit sheets but I'd rather have something made for my airbox. I looked at the mountain peformance site as well and found nothing. Maybe I'll have to call them? otherwise anyone know of anyplace else to look?
didn't see your post there ExpertX...I have to go now but I'll check out the outerwears later today. If it works, then it sounds like a good deal for $25.

my brothers did the same thing the other nite, just make sure your "ram air" vents beside the headlights are completely sealed and that takes care of the problem, hope it helps
they used to make powder pre-filters for the vipers. they go into the air intakes under the windshild beside the headlights. brother has had a set on his viper from soon after he bought it. it did like yours did and this has prevented it from doing it since.
here is a pic of his sled.

My ram air vents are currently packed in with snow and ice. They have been that way for awhile...it's been so cold lately that they just stay that way. I haven't bothered to clean them out. This kind of confuses me, unless they open up again while riding snow wouldnt be able to enter there. Would it be possible that the underhood intake vents are part of the problem, with the melted snow off the pipe and engine finding its way to the airbox? There was alot of ice on that foam.
hard to tell. the lake we where on at the time was 4' of pure powder and i was stuck with the 410. we where double riding back to camp to dry out when he found this. he just beat the foam on his leg to get rid of most of the ice and snapped it back in. sled still runs great and he has never had the problem since putting in the filters and he has ridden in similar conditions.
There are a number of other places for snow to get in besides the ram air vents. See all the posts about the dreaded BOG.
The prefilters help a lot. I have run them for some time. It does not cure all though, as there are other issues with bogging in deep snow riding.
