Whether you heard about spark plugs before or not, you should know that these small parts are very vital to the engine’s performance. They play an active role in how the car functions – in fact, without properly working spark plugs, your car would not be able to move at all.
These tiny items ignite the air-fuel mixture in the cylinders. It is worth knowing that over time, they wear out, become contaminated and eventually fail, which is why they need proper maintenance. But before we talk about that, let’s define spark plugs and their function in the vehicle.
What are spark plugs and how do they work?
A great way to describe spark plugs and their function is with the lighting example. Just like a bolt of lighting, these little components produce a spark, creating the ignition for the combustion needed to start the car.
Their direct function, on the other hand, is to put the engine’s pistons in motion so that the car can power up, stay powered and produce a smooth burn of the air-fuel mixture. Spark plugs withstand extreme heat and pressure within the cylinders (where they are located) and are designed to burn off any deposits from the fuel additives or other contaminants.
In other words, no car can start or go anywhere without a spark. Hence, the “lighting” that these items bring is directly linked to engine performance. However, that is also why spark plugs can fail and cause problems to vehicle owners – whether it’s issues with cold-starting or fuel economy.
What happens to spark plugs over time?
Spark plugs work well and have a good lifespan which is thousands of kilometers. However, these small elements withstand extreme temperatures and conditions to stay intact, not to mention the abuse they get when accelerating. This is why it is important to have top-quality spark plugs in your vehicle – the stronger their material is, the more durable and long-lasting they will be.
Naturally, every spark plug is designed to withstand wear and tear, but none of them can last forever. There are two main reasons for that – one is the deposit buildup which occurs from the interaction with the air-fuel mixture, and the other is the gap that the plug ignites to provide the right level of combustion. While the gap is widening over time, the buildup also shows wear and tear as a result of extreme temperatures or debris.
Replacing Your Spark Plugs: When To Do It & Why
The primary benefit of replacing your spark plugs is knowing that your car will have no problems to start. However, that is not the single thing that matters – there are more, including:
- Better fuel economy: According to studies, misfiring spark plugs can reduce fuel efficiency by 30%. Therefore, new ones are the best way to maximize fuel economy and save some money.
- Production of optimal combustion: A well-functioning spark plug equates a properly working combustion system. As a result, you will see less performance issues as well.
- Smooth start: Turning the ignition with a new spark plug is a surefire way to know that your car is starting. In many cases, old spark plugs are what causes problems with starting the car.
- Reduced harmful emissions: Regular spark plug tuneups can save gas but also contribute to the environment and reduce air pollution.
When it comes to spark plug replacement, the kilometer count for replacement is based on manufacturer service interval and fuel quality. The range can go from 30,000km to 160,000km. Ideally, you would want to choose the same brand and model that your vehicle was originally equipped with.
