Engine bay completely fills with snow anytime we hit powder. Air filter plugs solid with snow and ice to the point it won't run.
Any fixes for this?!

https://outerwears.com/dp/2002~YAMAHA~VIPER~20-1304/ is what we run on my dad's sx venture (factory 2 up sx viper) air box lid cover
https://outerwears.com/dp/YAMAHA~VIPER~20-1879/ is what my brother has on his 02 sx viper in the ram air vents.
both work well and keep water/ice out of the air box. i reccomend the 1st one. as to the snow under the hood, we tend to run 09 apex mountain skis on everything witch helps keep keep the nose up in the powder.

- Check hood fit, both on belly pan and airbox.
- Make sure hood parts are not broken.
- Block off vents below bumper when in powder.
- Run a fine mesh filter over the foam on the airbox or consider blocking off induction scoops beside the headlights.
- Use mountain skis. This was a huge difference.
- I also found an exhaust deflector necessary to avoid bogging.

"Ram air" vents are blocked off already.
Used frogzskin on big vent in front of exhaust pipe, and used smaller pieces on the hood side of the intake.
Did nothing literally 5 minutes in powder and it was un-rideable, air filter completely plugged with snow.
This is ridiculous as it's a "mountain Viper" . How did Yamaha ever get away with this BS back in the day. Bone stock low mileage sled aside from a trail can. Already has wide mountain skis from previous owner.
I'll try the outerwears thing but haven't heard of the Exhaust deflector. Could you elaborate on that one? Thanks for the replies.

Is yours a true mtn viper or an extended shorty? Many differences between the two as to air intake. The exhaust deflector is Yamaha part# 8EN-2194H-00-00. No longer available, I tried to buy the last one out of Japan last year and someone beat me to it. I have an 03 and an 05, stock exhaust, and never had the issues your experiencing and we ride mountains and powder. 8EN should be the prefix on your vin for the mtn model, not sure for Canada

Yes, factory MTN. Not extended.
Your sled should have the deflector from the factory, check and see. They can dislodge themselves. I see you have an aftermarket silencer and I am a firm believer in sealing the exit hole with high temp silicone, stock or aftermarket. Shine a light up from below and see how much it isnt sealing and check the rivets and fitment on the bellypan seems. Looks like snow is packing heavily in that are. I may have a pre-filter available if you cant find one.
