The deciding spark
In a gasoline engine, the spark plugs ignites the gasoline-air mixture at a well defined point in time. With repeated use, the spark plug becomes dirty and the plug changes in appearance. Because of these sediments, the distance between electrodes gets bigger, so the ignition coil has to deliver higher voltages. If the required voltage cannot be produced anymore, spark failures are the consequence. At this point at the latest the spark plugs have to be changed.
Cheap plugs may trigger preignition
When using cheap or unfit spark plugs, the effect of the preignition may occur.This is an uncontrolled burning process, which may lead to damage in the ignition spark and the engine. When you buy new spark plugs you should look for compatibility and high quality materials for this reason. The instruction manual of your car will tell you in what intervals you will have to change the spark plugs. Spark plugs should be checked once a year at the minimum.
