We have seen so many films where the reason why cars stop on the street or right in front of a handsome mechanic’s workshop is dirty spark plugs. But apparently, the cinema hasn’t done enough: most people never think about spark plugs and their function if the engine has problems. Yet these small parts play an incredibly important role in the operation of your car.

Quality spark plugs provide the spark
The spark plugs are car parts that provide the spark that ignites the air/fuel mixture, creating the explosion that allows it to produce energy.

In fact, without properly working spark plugs, your car most likely would not be able to run at all. In this article, we want to take a closer look at why spark plugs are so important, including what they do and how to know when it might be time to replace them.

What do Spark Plugs do?

Your engine is a truly remarkable system, designed to transform a source of energy (gasoline) into real motion. But have you ever wondered how it does it? The answer is the principle known as internal combustion. To turn the fuel in your car from a potential energy source into a kinetic energy source, the engine needs to find a way to release energy, and it does so through the combustion process.

The best spark plugs in the world and why

The engine cycle is what makes this process possible and, in this cycle, the valves fill the cylinder with a mixture of air and fuel (which are highly explosive when combined). As the engine piston moves up, it compresses this mixture until it comes into an extremely small space, creating even more potential energy.
