I know that Ford puts them on for free in 15 cold weather states and is standard, MI is one of them. I got mine and it was on the sticker with $0.00 cost. It is a option in the other states. Here are the states that it comes standard in, the truck must also have been ordered for that state to get it for free:AK, CO, IA, ID, ME, MI, MN, MT,ND, NH, NY, SD, VT, WI, WY.

If you have to order it and pay for it from Ford, it cost $75.
