The coil on my car puked and died shortly before I bought the car from the previous owner. My research confirmed what you've already read here. Keep the coil away from heat. I also learned that unless you have a specially designed coil, it also needs to be mounted vertically with the wires at the top. If you must mount it where it is exposed to heat and vibration, or where it is not mounted vertically, there are special coils built to withstand that abuse.
