What is the car spark plug used for?
The spark plug is one of the simplest components of your engine but it is also one of the most important. Even though the auto industry has over 140 years of engine technology innovations, without the spark plug we could still go around in the gig.
Of the spark plugs for cars that give more performance, they can also make a big difference in driving and ensure the proper functioning of your car. Think that when these products are no longer able to work at their best they can reduce the efficiency of your vehicle by making you consume up to 30% more fuel.
How do spark plugs work?
Just insert them into the cylinder, plugin, and “turn them on”. Said this is simple, in reality, their use is a little more complex. First of all, a candle is an electrical device. It fits into the cylinder head of a gasoline engine, also powered by LPG or methane. The head of each cylinder is flooded with a mixture of air and fuel (petrol, in fact) which the spark plug ignites by means of the spark.
This small explosion – not surprisingly the petrol engine is called a combustion engine – moves a piston that is connected with cams to the crankshaft which transfers energy, with other connections, to the wheels of your car, pushing the vehicle. If there were no spark from the spark plug there would be no combustion and without combustion, there would be no energy to propel the engine.

What types are there on the market?
Although they are small and relatively simple objects, candles are not all the same. There are differences between the various models that you can find on the market. In principle, they all have the same design but it is in the materials used for the electrode and sometimes on the cap that you will find the differences. In fact, the electrode can be made of copper, platinum, and iridium.
Candles with copper electrode
Originally, copper electrodes were used and this material is still used for the production of standard economic type spark plugs. In modern cars, copper spark plugs are replaced by platinum or iridium electrodes. These two materials have better performance and even better durability.
Keep in mind that modern engines that need cranking cannot perform well with copper spark plugs. However, older motors can sometimes work better with copper and are still being manufactured for this.

Candles with a platinum electrode
It is a mid-range material, which offers a higher performance increase and fuel economy than copper, with a lower cost than iridium spark plugs. If you want an increase in the performance of your car, look for spark plugs that use double platinum in both the electrode and the cap.
Spark plugs with an iridium electrode
The pinnacle of candle technology is now achieved with iridium. Spark plugs with iridium electrodes offer the best performance, the best fuel efficiency, and longer life. For these better performances, they have a much higher list price.

When should the spark plugs be replaced?
While you don’t have to change them often, candles don’t last forever. Typical copper ones wear between 15 and 30,000 km. The platinum ones allow you to travel up to about 80-100,000 km, the iridium ones can last up to well over 120,000 km.
A periodic check of the engine parts, including spark plugs, allows you to evaluate the state of wear and if they are just dirty to clean them. Do not wait for the spark plugs to be completely worn or deteriorated, as this will affect engine performance and fuel consumption.
These are the signs that can occur when the candles begin to lose their efficiency.
Difficulty starting the engine: You notice this when the car struggles to start and rev, especially in the morning.
Uneven idle: we are all able to hear how the car engine is spinning, right? It should be a nice, even sound. If the sound is too loud or erratic, the spark plugs could be the cause.
Missing: Improperly installed spark plugs will not help the air-gas mixture ignite, causing the engine to miss.
Poor acceleration: if you step on the accelerator when the green light comes on and you feel an asymptomatic jolt as the car starts to run, the problem may be the spark plugs.
Poor fuel efficiency: An engine that runs with old worn spark plugs will simply not run efficiently. If you notice that you are getting less mileage with each tank, it may be time to replace the spark plugs.

How To Change & Inspect Spark Plugs | Video Explanation
The thermal degree of the candle
Candles can operate at different temperature peaks: cold candles have colder peaks, hot candles have hot peaks. The relationship that describes the ability of the candle to dispose of heat is called the thermal degree. The amount of heat that develops in the combustion chamber of the cylinder varies from engine to engine: in the less performing engines of small-displacement cars, it is less, while it is greater in engines with higher performance. The resulting heat actually causes the temperature of the spark plug to rise and must be dissipated.
The external part that has a negative function (it closes the ignition circuit to ground on the engine), is made of metal and is connected to the cylinder head, so it dissipates heat very quickly. The problem lies in the positive, which is separated from the external metal body by an insulating structure (generally a ceramic body), and it is precisely the shape and composition of the insulator that largely determines the thermal degree.
The insulator collects the heat in the combustion chamber and conducts it towards the top of the spark plug and then transmits it to the external metal body and then to the engine. At all points where it comes into contact with the metal body, there is a transfer of heat. By enlarging or reducing this contact surface, therefore, the greater or lesser amount of heat dissipated by the spark plug through the body can be defined.

Cold or hot tips?
Cold tip spark plugs are best used on very hot days and are best for high-performance, high rpm engines – the tips cool down, so they run at a lower temperature, allowing the spark plug to dissipate heat excess from the engine more efficiently. Hot tip spark plugs work the opposite – it means they are always hot even when the air introduced into the engine is cold.
This is important because if the spark plug operates in an environment that is too cold, the combustion in the cylinder head will not be as efficient as it should be. This in turn affects engine performance and can lead to accumulated dirt deposits on the spark plugs which shorten their life.
Such attention must be paid to the choice of candles to prolong their life, if you live in an extremely cold climate or, on the contrary, extremely hot, but in our climatic conditions there is no need to worry much about temperatures, except that upon checking the spark plugs are not worn.

How to inspect the candles
Removing the candles from their seat is relatively simple.
Once you have disassembled the candles you can check their condition by looking at their look. If they look good and the engine runs perfectly, the spark plugs are fine and you can refit them.
If they have a simple reddish patina, it may be that there is some residue of residual additives from not perfectly burnt cheap gasoline. The engine still works well, just clean them with a cloth and reassemble them.
If you notice signs of wear, burns, or black spots, bubbling on the ceramic body or the electrodes seem worn, i.e. they are thinner than those of a new spark plug, it is time to replace them.
Basically, if the electrode is fine and after simple cleaning, it seems normal to you, the spark plug is probably fine too, because it is mainly the thin electrode end that is the working part of the spark plug.
How to clean car spark plugs
If the spark plugs are dirty and the contacts are worn, the spark that ignites the mixture of gasoline and air in the combustion chamber is not generated correctly: in this way the battery also gets tired and the engine suffers, causing other anomalies.
The simplest thing to do is to clean it. It is an operation that you can do very well yourself, removing grease dirt and any oxidation from the electrodes with a brush, a rag, and a little ethyl alcohol. Before proceeding, make sure that the engine is well cooled, remove the cap of the pipette, remove the spark plugs with the special keys, check them and then replace them in their place in the respective cylinder without tightening too much so as not to damage the thread.
