I've had a lot of vehicles with heated seats (European, Japanese and US) and these are BY FAR the hottest which is one of the reasons I chose them. My wife (love you dear, really!) has a comfortable temperature range of +/- 2 degrees. Anything I can do to keep her BTU level topped up during the winter only makes my life better
I'll work on the write-up this weekend and post it when done. Great mod for those of us in cold climates.
