Conditions inside an engine are predictably brutal. As much as modern engines are engineered and built to reduce friction among moving parts, friction – and the heat that goes hand-in-hand with friction – is unavoidable as cylinders get pumping. Depending on engine speed, spark plugs fire 1000 times or more every minute. Wear and tear is a real issue.
No matter how efficient an engine is, a tiny bit of material is left after each combustion. These deposits build up on the spark plugs over time, resulting in uneven performance and even lower gas mileage. In addition, the gap that a spark has to travel to ignite the fuel/air mixture gets larger and larger as the spark plug ages thanks to heat, particulates and normal wear and tear.
That’s why it’s important to have your spark plugs checked (and replaced) according to the manufacturer’s maintenance schedule. Superior materials may have extended the average spark plug’s life, but they won’t last forever.
