They are quite effective in the lower radiator hose. Not quite as good as the OE heater in the block but good enough to warrant avoiding any work on the plug or OE heater. I have one in my 123 and 116. It'll be 8 below zero in the am and I'm confident both will fire right up.
Edit:
It was 17 below zero this morning and the 116 with a lower radiator hose heater started right up. Didn't try the TD until later in the morning.
