How Often Should You Change Spark Plugs?

Spark plugs are small yet vital parts of an engine responsible for transmitting the spark to ignite the compressed fuel-air mixture. The most common reasons for changing spark plugs are wear and tear, fouling, and improper gap.

If you don't know how often to change your spark plugs, here are guidelines on how often a professional can help you do this maintenance.


What Are Spark Plugs?

Spark plugs are the tiny pieces of metal that produce the spark needed to create combustion in an engine. They consist of a metal wire and electrode. A car's engine needs a spark plug for ignition. If you don't change your spark plugs regularly, it can lead to problems, such as reduced gas mileage, reduced power, and even engine failure.


How Often Should You Change Your Spark Plug?

The time it takes for a spark plug to become worn out depends on many factors. For example, the type of engine oil, recommendations of the manufacturer, and how regularly the vehicle is driven all play a role in determining when you should replace a spark plug.


The lifespan of a spark plug can vary from 30 to 50 thousand miles. It depends on the factors above and how often you change the oil of your vehicle.


Spark plugs are necessary for any combustion engine to operate. They provide a mixture of combustion with a high voltage that will ignite it. It creates heat and pressure, and thus fuel is turned into power to move the engine. Without spark plugs, your car will not function.
