RMK Intake Vent Issues

I have a 2003 700 151" RMK with some minor mods and had some issues while riding it yesterday.

The sled has an SLP high comp head for my elevation (1200'), PSI y-pipe pipe and can, SLP intake and the SLP high flow intake kit. It is jetted and clutched well for my riding style and elevation and usually runs great. I was riding yesterday and it ran great when we were riding in places where there wasn't a ton of snow, places like where there were already tracks to follow or on the trails.

We were riding the UP of MI where they have anywhere from 18-30" of snow over the past week and when we'd find a place with untouched powder, the sled would start bogging and running like crap. I noticed that it ran bad every time there was snow coming over my windshield for a while because the four intake vents would get covered with snow. I checked the airbox for signs of snow in it and there was none getting sucked in so that didn't seem like the issue. If I cleared the snow off the intake vents, the sled would bog for a little longer then start to rip again until the vents got covered again. It seems like the vents arent enough to get sufficient air to the airbox but theres not much for options left as far as places to add more intake vents cause there just isn't much room left with the four already in place. I still have the speedo in place but wouldn't mind losing it but the issue with just adding a speedo intake vent is that was getting covered just as fast.

One of the sleds I was riding with is an Edge 800 RMK and that one has the stock intake vents but also has a speedo intake vent. That sled was having the same issues I was having, bogging every time we were playing in the deep stuff for very long. He would do the same thing, clear off his speedo intake vent and it would start to rip again until it got covered up good again. We were the only two sleds with the balls to stay in the deep stuff, the other sleds with us would just sit and watch so IDK if they would have had similar issues or not. Underhood temps were fine for me all day, I've never had an issue with those and this is the first time we've had enough deep powder in the UP to have these issues with intake plugging.

What options have some of you guys that are used to really deep pow used or tried? There's gotta be something that'll help, it's an RMK for chrissakes, it should be able to handle 3' of pow and snow coming over the hood for miles. The guy that was plugging his 800 is also wondering what he can do, we love riding the deep stuff but it sucks when your sled starts bogging every time you're starting to have fun. Both sleds have windshield bags, FYI but if you guys have any good ideas, it'd be much appreciated. Thanks in advance.
 
Were you booging in mostly right hand carves?
Or were you bogging whenever snow came over the hood?

If you noticed it was a right turn bog then it's probably your exhaust deflector.

If it's the other then you might need a new foam donut on the airbox
 
It only happened when the dash vents were caked with snow, no difference in turns. I'd clear off the vents and after a short time of them being clear of snow, it'd start to rip again. I also know the foam donut is fine, it's still in good shaped and not crushed or misshapen.
 
Those vents look awesome, I ordered 2 of them that will be added to the side of the airbox and I also have a speedo flo rite on the way, got it dirt cheap and maybe it'll just take a little longer before the dash vents are all plugged up with the speedo vent too.
