Exactly what I was saying... I do not have a CAI but, the DIY intake, K&N and TB bypass, it was not even cold outside in Quebec(0°C) and was having trouble to get to the right temperature, I also needed to keep the heater off before leaving with the car.-30c (-22f) here yesterday and -25c today, no problems with my cold air intake.
I do need to keep my heat off\low for a while to get up to full operating temp though, I'm unsure if that's actually related to the intake though.
I don't see how your OP question is not answered... Yes it's okay to run CAI in cold weather, and if you are afraid about the water, then just spend ~$20 and get a hydro shield from Injen for peace of mind.My questions wasnt even answered i live in MA i dont want to suck up water!
