P22. When increasing the compression tax must I substitute the original spark plug?

When increasing the compression tax we will be increasing the chamber pressure in the combustion chamber, therefore we need a spark plug with better colder ignition and to waste the increase of heat in its igniter tip, provoked for the pressure increase.

Thus, for determination of the thermal degree of a spark plug the measurement of the temperature of the igniter tip of the same one is necessary, in some situations of functioning of the engine, however these tests and assays alone can be carried through with appropriate equipment.
