The fact of the matter is that the spark plug in this country is very nearly the highest priced in the world.
My wording allows, for example, for the sale of a spark plug, which, we can all agree, is a motor supply, and also the spanner to remove it.
The other set ran on a single cam on the same shaft for triggering the spark plug on overrun.
There it is aimed at the spark plug area and ignited.
A spark plug is said to be cold if it can conduct more heat out of the spark plug tip and lower the tip's temperature.
If the tip of the spark plug is too hot it can cause pre-ignition or sometimes detonation/knocking and damage may occur.
Whether a spark plug is hot or cold is known as the heat range of the spark plug.
The exact terminal construction varies depending on the use of the spark plug.
