Spark plug replacement

By Julia Freeman

For most people who are not mechanically minded, the way in which a car's engine works is something that they rarely think about - until the day it stops working, of course. Most of us have heard all the technical terms but rarely pay much attention to them. The spark plug is a prime example of this, almost everyone has heard of them, but not so many are aware of exactly what they do, just how essential they are to the starting and running of an engine, and that they wear out and need replacing more frequently than most imagine.

The Spark Plugs function.

As the name suggests, the spark plug delivers the spark that ignites the fuel. An internal combustion engine runs on a series of controlled explosions. In an engine, each cylinder will have its own spark plug. They work by arcing a spark between two electrodes causing combustion between the air and fuel mix which drives the pistons. Each time this happens, tiny amounts of the metal are burnt off from the tip of the spark plug, lengthening the gap the spark needs to jump to connect. Of course, over time this will slowly reduce the efficiency of the spark plug until one day the inevitable dashboard warning light comes on. Before that happens, it is worth consulting us at Protyre, the local garage you can trust. In our experience, this can often save you the hassle of a non-starting car or being stranded somewhere - a scenario nobody wants.

As with most things to do with a car, the manufacturer's guidelines should always be adhered to or a professional should be consulted, which is where our team at Protyre, comes in.
