Do you Wisconsin boys not have gloves? Mine takes a little longer but I am on highway in less than a mile so it’s not much different. The diesel is very cold blooded.3.7 miles granted it was a bit warmer on my trip to work. Trip milage improved roughly 3 mpg even with light rain on and off. Intake temps were about 15-20 degrees above ambient as opposed to normal 2-5 degrees. Will take pic of my hack job in the morning if I remember. Will paint the edges when I get a chance.
