Invented more than a century ago, a spark plug remains one of the key components in a gasoline engine. Using the same principles and design patterns introduced by Robert Bosch’s employees at the dawn of automotive era, the plugs have greatly evolved including their materials and performance. But still, because of severe environments and heavy stresses, the plugs have a limited service life, whose length differs substantially depending on engine performance and condition, operating modes, quality of fuel and, of course, quality of the plugs themselves.
Depending on their heat range, plugs can be “hot” and “cold”. The former get hotter during engine operation, but they better resist carbon buildup. The latter get not so hot, which allows them to be used in higher temperatures (higher RPM). Like any other gasoline motor, the engine installed in your Volvo S40 is designed to operate with the plugs featuring a definite heat range. Filling tank with a high-quality fuel and using the right plugs by well-known brands, you can expect the plugs to be very long-lasting. However, they won’t last infinitely long. Failing spark plugs reduce power and cause misfiring and rough idling after the cold start. Having noticed something like that, you shouldn’t hesitate with installing new Volvo S40 spark plugs. Not only because it saves fuel and money, but also because it prevents a number of mechanical problems and keeps your car eco-friendly.
