If the whole point of a cold air intake is to cool the air prior to ingestion, so it's more oxygen dense, then why tf does the MPG go kaput in the winter. Shouldn't the engine be stronger sucking cold air?
1 mpg difference over a week is like +250 bucks...

In off road conditions, the crossmember bolts get loosened up. BEfore retightening, take those out and replace them with fine thread flange bolts class 10.9 or grade 8. Say goodbye to a boring life

Due to a mix of # 1 and # 2 diesel. The more #1, the colder you can go but MPG goes down. Beats gelling up.

Mine usually tanks .5 to 1 mpg in the winter. I track my fuel tank to tank - last 5 years, religiously. Never fails.

Yeah kinda sucks all around. Winter fuel is less efficient, but hopefully your bunk heater will off set that. Summer fuel gets better mileage, but you may see more idle which off sets it. ####'d if you do, ####'d if you don't.
