Here are your questions about a spark plug answered!

Spark plugs have an important role to play in running your car’s engine. Internal combustion specifically depends on the compression and ignition of fuel. However, compression is done by the pistons, while ignition is the duty of spark plugs. They offer the necessary spark to the air and fuel mixture to ignite the same.

But, over the years of service, the spark plugs usually suffer a lack of efficiency. A spark plug usually contains two electrodes that share the necessary electricity between them. However, when sparks travel from one electrode to another, it actually hurts them a bit and results in gradual wear and tear.

Sometime, the electrodes become so wide that they cannot exchange the current properly, and your car might start to experience issues at one point in time in future. It often produces consequences such as reduced gas mileage, lack of acceleration, and even misfires. Eventually, you get the check engine light on your dashboard.

When do I need to check for a spark plug?

Usually, spark plugs are meant to be in a proper state after approximately 50,000 kilometres, although some of them may serve your car up to 100,000 kilometres.

However, you can get a better understanding of a spark plug by examining it physically. There could be a gap between electrodes wide enough because they may be burned off.

After running for a considerable distance, either the spark plug electrodes might be in worn condition or there could be some sort of deposit on them. In any condition, the spark would not be up to the mark and definitely suffer. However, the ECU (Electronic Control Unit) takes care of minor adjustments to manage the air-fuel mixture and spark timing initially.

But, this might be a sort term solution until the engine starts to show signs such as loss of performance and increased fuel consumption. If you opt for spark plugs replacement on the basis of assumption, it will not provide any benefit unless your car’s engine shows any problems.

What makes a spark plug so essential for an engine?

Internal combustion engines specifically require ignition to complete the process. But if there is any problem with sparking, the combustion may suffer. Therefore, a car is nothing without a working spark plug. This places the spark plug on the list of critical components.

If you have become the owner of a pre-owned car or have been using it for more than a decade, you have to be extra careful to pay attention to the car’s spark plug.

However, manufacturers have become serious about the quality of spark plugs as they might cause an engine to misfire. And a misfiring engine can produce a lack of power, which could be hazardous for a running car on the road.

But, the quality of spark plugs also matters, as inferior quality might not be as efficient as a spark plug should be. They cannot be helpful in reducing fuel consumption either because a faulty or low quality spark plug will not provide proper ignition when there are high requirements at high speeds.

Though the modern car is equipped with durable spark plugs that do not wear out pre-maturely, not less than 100,000 kilometres under normal circumstances, But, when they start to approach the end of their lifespan, the gap between two points definitely starts to widen up due to the constant loss of metal from the electrodes. Once this starts to happen, your car might start to show symptoms of problems, either in the form of misfiring or even a lack of power.

It signals you to be active before you face trouble while riding on the road, and more specifically, before your car’s engine starts to receive damage.
