Viper prefilters
Ok, I just finished the install. Not enough snow locally to test. A screw through the windshield bezel is needed to pull the leading edge of the duct over to prevent any snow from getting by. This ram duct kit came from the dealer as genuine Yammie parts. I don't have the P/N sorry. You have to install some velco on the duct then attach the pre-filter material. The reason I put them on was to give the air box some cool fresh air not the hot air within the cowling. At least both my MMax's took fresh air in through a pre-filter forward of the handle bars. I thought this kit is going to be even more important when I put on a set of tripple pipes.
