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.
