My buddy has this vent and I’m stock. This last weekend we both seemed to clog up equally ie - didn’t seem to help.
I suppose if a guy wants more intake surface area the only other option would be to drill a hole in your hood and add a snorkel... but heres my crappy take on it- if the Ibexx vent is not helping you likely have other issues creating the bog- collapsing charge tube or exhaust bog.
For next season I am planning to do a left side Ibexx vent, aftermarket charge tube, and a tunnel dump. Hopefully that eliminates all the possible issues and I don't have to worry about it.
I've heard from multiple people that the Fire N Ice under hood draw vent does nothing. I have no experience with it... but I would think more surface area would be needed, but then you are likely drawing a fair amount of hot air.
Chadly is correct, Doo has it figured out. Rode a couple extremely deep days on my Gen 5 and never had a single issue. 12" of snow rides on top of those vents and gauge... it doesn't even make sense that it works ?
