    It is not necessary but nice to have. Anything under 0 degree f and it is really nice to have. No problems with the car wash either, i always use the touch less in the winter. If you dont want to use the cover, you could insert a piece of cardboard or something between the active grill shutters and the CAC if you wanted to and remove it pretty easily to. I did that today because -20 sucks and im tired of the truck not getting past 170 degree. Sometimes those 4 holes in the cover is too much.

    Temperature here right now -15 Celsius which equals 5°F my truck running at 93°C which is 199°F I have no winter front on

    what's up with that ??

    Don't you normally run loaded with several hundred pounds in the bed and tow frequently? You also drive 2-3 times as many miles a year than most people.

    Winter front makes a difference when your not working the truck. Everything warms up quicker and doesn't lose that heat when you slow down and/or stop.

    Down here in south Florida I seen the semi sod haulers will run partial winter fronts all the way till May , which temperatures could be 80-90f , now common sense comes into play ,as long as your not over heating or running it excessively hot , diesels love heat !!!! They burn cleaner and more fuel efficient, remember their combustion ignition, no spark plugs ,they rely on heat to fire off efficiently. Especially the short distance drivers as long as your not running it hot , you are not going to hurt it . Now you do have to make sure your electric fan isn't constantly running to compensate for your cover .
    Just pay a little attention to when the electric fan turns on vs driving distance.

    Yes I do carry weight and or a trailer a lot of the time
    However it does not make much difference to the temperature more than a few degrees
    I'm pretty sure my temperature record runs around 90 to 96°C most of the time although I don't sit and stare at gages worried about a few degrees or whatever

    That is the point, your always giving your truck a workout, generating a bunch of heat. Not everyone drives as much loaded as you do, that why it doesn't make much difference for you using a winter front.
    Running unloaded, staying under 65 mph in 10°F(-12°C) weather with a winter front makes a big difference.

    The Ram 1500 is the first truck to use an active grille shutter system (similar to the one on Dart), closing airflow through the grille when cooling is not needed. It increases gas mileage by 0.5%, cuts drag roughly 4%, and cuts warm-up time/defrost time. The computer closes the shutters when cooling is not needed.
    Dave Sowers pointed out that the active shutters was normally either fully open or fully closed. When closed, air pressure quickly builds up in front of the slats, deflecting oncoming air over the truck, which has the lowest drag coefficient of any pickup on the market. At all times, there’s airflow over the radiator from other openings. The idea was to avoid drag from radiator capacity which is seldom needed, while still being able to cool the engine under any reasonable conditions. (He also said that riding with the tailgate down increases drag, while a tonneau cover makes the truck much more aerodynamic.)

    And that is why I thought only covering the bottom where there is no active shutter was a good idea. Let the truck control the temperature. Unfortunately my truck doesn't get the work out these ones require with many very short cold trips in the winter. I have noticed much faster warm ups for my very short trips by covering the bottom grills and plugging in. When the truck is on a long hard haul it doesn't matter. Just me but I've never had any luck with "Car Bras". I'm skilled at getting them off just can't put them on

    The myths still going strong at this Site....HPCR do NOT like, need or want excessive intake heat.... all these coolant temps are regulated in the 3.0. NOT 1 mention of the intake temps in this thread, or the 100+ others at this site. Your coolant valve will regulate and distribute the volume necessary to control TRANS,OIL,COOLANT EGR temps. the cooler the intake air the more efficient combustion on all HPCR diesel engines....if you want to run the OE WF go for it in temps above 0F, thinking the coolant temps have any benefit on input to the engines operation is foolish.

    Intake Heat kills combustion on any bluetech motor, it increase the flame temp = more NOx more soot and less HP = less MPG ,ALL IN THE NAME OF WHAT!!!!! HOTTER COOLANT TEMPS, the EGR chamber can easily boil the coolant ( its capable of 300+F exhaust heat) the heat needs to be cooled in the process the heat warms the coolant. the coolant is also used to exchange heat Oil/trans Fluid.....

    decades back Diesels need additional heat to ad combustion in aspirated engines, HPCR system controls injection(s) events More heat is generated by TDC timing. the hotter the intake air, the system will retard timing generating less heat to lower the flame and NOx soot. IGU.

    Your truck, Your money. Your choices.
