I bought mine when I was at the show in the states, but I dont remember who I got it from, I will ask my buddy if he kept his paperwork. They look like they will be awesome but I did wrap mine with some stretchy material as the hole under the guage will pour the snow under the hood. I will let you know how it works as it wasnt cheap, I think I paid over $120 bucks for mine.
Installed a Gage Cage on the M8 quick mount up, opens up a nice area for the heat to get out. I agree may place some screen across the opening to prevent the snow from getting in, they also come in black as well. AMP
These are supposed to be out at the end of January as well. Thought they looked pretty cool. You can get them without the side gauge pods as well if you don't want them.
