According to the expert, Spark plugs with excessive wear or irregular functioning can cause engine failures, in addition to difficulties in starting the car, increased fuel consumption and pollutant emission levels.
"The irregular operation of the spark plug is not always noticed by the driver. Due to technological evolution, the engines are conditioned to work in adverse situations and, principally, When there is a failure onset. When the problem begins to be noticed, it's a sign that it's been happening for some time", alert the expert. The component works under very severe conditions, such as high temperatures and pressure and, with use, suffers a natural wear and tear.

Possible engine problems, like excess fuel, Oil and coolant seepage into the combustion chamber and poor fuel quality use can also be identified by visual inspection of the spark plug. NGK's Technical Assistance consultant explains that the appearance of the part says a lot about the condition of the engine and, that's why, should be prioritized in any preventive review.
