Not saying that's a whole ton better, but I was a little surprised when you threw the figure of -50 out there.
In response to that, he may have slightly harder time getting it started, but once it's running how would it really be that much different than that of the factory airbox? Wouldn't it be just as affected by underhood temps as an airbox with a filter in it?
Not saying it's the most ideal setup, but I just don't see it being detrimental.

I'm just gonna pitch a rather dumb idea that could work. How about 2 different intakes, 1 hot air, and one cold air, and you manually switch from the hot air to cold air intake by a switch once you reach operating temp. Seems crazy but could it work? Especially for people in really cold weather.

Just playin' devils advocate here... but after a quick little 5 minute or so search of average temps in wisconsin from 1971-2000 it appears that the lowest average in the northernmost portion of the state is about -30*f

I know it's not ideal. But it was free, took me 10 minutes, and is less restrictive. I'm still drawing up my actual setup in autoCAD, which will be a true cold air setup. It will get fabbed up in the spring.

In order to get an average of -30, there has to be a few days of -50...lol

I didn't think about the intake being a moot point before the motor is warmed up, but that itself is a moot point as I was trying to play advocate for the poster about his intake to begin with.
I will say that these work better when you can completely isolate the air going into the filter. Either through the cowl or by making your own box which draws outside air in as opposed to under hood air.

True. Honestly I was just spitballing man... my thing is, I don't know why people get so hung up on the whole intake thing. Yes, it has its drawbacks, but there are those who run them and have seen results. I have one on mine, it's a K&N and it was in it when I bought it. Would I shell out for one? No. Would I make my own? Yes, but I would run it into the cowl myself - namely because there is a lot of water here in florida and while I've been fortunate enough not to sink my intake filter in it YET, I don't want to take that chance.
