The spark plug is one of the most important parts of a vehicle. As its name suggests, the role of the spark plug is to produce a spark. That spark then ignites the air/fuel mixture in the engine. Subsequently, an explosion occurs within the engine. The explosion produces the power that subsequently runs your vehicle. This process repeats itself endlessly (while the engine is on) — to keep the vehicle running.

In the absence of a spark plug, there would be nothing to ignite the air/fuel mixture in the vehicle’s engine. And if the air/fuel mixture isn’t ignited, there is no explosion within the engine: meaning that no power is produced.

Features of a Spark Plug
- One of the most important features of spark plugs is the insulator.
- This has an impact on thermal conductivity.
- It also affects the dielectric strength.
- Another important feature in spark plugs is the ground electrode.
- This can affect the plug’s safety and durability.
- Yet another important feature in a spark plus is the center electrode.
- This affects the plug’s overall performance.
- At a practical level, ideal spark plugs would have the correct gap and be easy to install.
- It should also be capable of supporting optimal engine performance.
Types of Spark Plugs
- There are four major types of spark plugs: iridium spark plugs, copper, pulstar spark plugs and platinum spark plugs.
- Iridium spark plugs tend to have better performance than platinum spark plugs, but not as good as pulstar spark plugs.
- Copper spark plugs are usually available at lower prices.
- But they may have poorer durability and somewhat poorer performance ratings.
How to use a spark plug?
- The first step is to ensure that the spark plug gap is correct.
- Some spark plugs allow you to adjust the gap.
- Others have gaps that are fixed at the factory level.
- For such spark plugs, it is impossible to adjust the gap.
- All in all, you need to avoid ending up with a spark plug gap that is too big.
- Such a big gap would mean that the electrodes are too far apart.
- Consequently, the spark would have difficulties moving from one end to the other.
- At best, that would lead to the engine running in a rough manner.
- At worse, it could lead to the engine not being able to run at all.
- So, first, ensure that the spark plugs gap is correct.
- The next step is to place the spark plugs into the hole meant for it on the engine block.
- Before doing this, you may consider cleaning the hole with a piece of cloth.
- You may also consider applying a little oil on the plug’s threads.
- Then slip it into the hole meant for it. Screw it in: taking care not to ruin the threads in the process.
- Finally, attach the spark plug’s cable, to complete the installation.
- Ensure that you change your spark plugs regularly to maintain good engine performance.
Buying guide for Spark Plug
- Ensure that the spark plugs you purchase are suitable for the vehicle you are purchasing them for. Carefully consider compatibility.
- Check the condition of the spark plug’s insulator and threads. Ensure neither the insulator nor the threads are broken.
- Go for spark plugs that come with the correct gap and are easy to install.
- Ultimately, you will have to choose between buying spark plugs from a local spare parts store and buying online.
- If you buy from a local store, you won’t have to wait for shipping: you get the plug right away.
- But you will probably pay more for it. Conversely, if you opt to purchase the spark plug online, you will probably find a lower price.
- But you will have to wait for shipping.
- Moreover, having opted to buy your spark plug online, you will have to wait for delivery to inspect it properly.
