That site will tell you what the latest version that is available for your vehicle.
If you are wanting a higher version, but it is not coming from that site, then you are playing with fire.
My 2020 MKZ Hybrid, is at 3.4 22200 and works just fine.... I'm hoping someday it will go to 3.5 or higher, but I'm not holding my breath for that. 4.0 would be kewl, but first it's up to Ford/Lincoln if they are going to offer that. as I understand 40 needs better and faster hardware that will not convert over (that I'm aware of)
