P21. When installing a compressing turbo must I substitute the original spark plug?

When installing a compressing turbo we are increasing the volumetric efficiency of the engine, therefore generating more heat in the combustion chamber and making it difficult the spark-out of the spark plug due increase of chamber pressure of the combustion chamber.

Thus, one becomes necessary the applications of a spark plug of better ignition and adjusted thermal degree the engine. 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.
