Are hot or cold spark plugs better?
The Hot Spark Plug is a better heat insulator and keeps more heat in the tip of thespark plug. Whereas, a Cold Spark Plug conducts more heat out of the spark plugtip and lowers the tip's temperature. A great surface area exposed to the hotcombustion gases. Heat transfer to the engine head is slower.
