The electric portion only reverts it to cold air.
You don't have to use the cold air.
I thought about restoring the OE thermostatic intake but I wanted something a little different.
Main difference with mine is I was never trying to flow full air flow through the WAI.
If I need power the CAI is opening.
Also I am going to be running 11:1 compression.
I will end up using 2 snorkels too.

If it gets so cold there why not just convert to an after cooler and just turn off the after cooler when it's really cold letting the turbo heat the air? While drawing air from under the hood.1)my Air to air will drop the temp to ~-40°f @60+mph at idle.2) I have my complete turbo up. Heat wrapped so after 100mi I can pop the hood and hold on to the turbo or "anything" without getting burnt (below~130°f) and this is with a 4-500°f EGT at the time(inside the manafulld). So no under hood heat to help. I was going to pull my warm air off the down pipe.3) thire is no heat produced by the turbo or under the hood with EGT of 50-150°f and no boost at idle.
That is what I was going to do when I thought I was moving to Montana or Wyoming.
Have you read the 5.9 stationary non intercooled application manual?
They recommend running cold air down to 25°F to freezing, then drawing air from inside the enclosure if operated below 25. this to keep the air form becoming too dense causing excessive back presser on the exost side of the turbo or stretching the head bolts. And the injection pump is calibrated for IAT~2-400°f and steady rpm @~rated (1600rpm)
