How Often Should You Change Spark Plugs in Your Vehicle?

The condition of your spark plugs plays an integral role in the overall performance of your vehicle. To keep your engine in top working condition, you’ll need to change out the spark plugs from time to time. Learn more about why spark plugs are so important and how to know it’s time to exchange them for a new set.

What’s the Function of Spark Plugs?

Essentially, spark plugs are responsible for igniting gasoline in the engine that allows the pistons in the engine to operate. This is done by producing a spark within the engine block that creates a controlled explosion that propels the pistons up and down. If one or more spark plugs are malfunctioning, your vehicle will begin to operate with diminished performance and can eventually cause long-term damage to your engine.

Signs that it’s Time to Change your Spark Plugs

When a spark plug fails, you’ll likely begin to notice several issues with the vehicle that are difficult to ignore. Recognizing these problems sooner than later will prevent other mechanical problems in the future, potentially saving you a lot of money on repairs. Here are some common signs that it’s time to change spark plugs in most modern

1. Engine Knocking and Misfires

When your spark plugs stop operating properly, you may notice unusual sounds coming from the engine block while driving. These sounds could include knocking, misfiring, and increased noise when idling. You may also hear the engine laboring more than usual to accelerate, especially when the car is at a full stop.

2. Difficulty Starting the Vehicle

Old or damaged spark plugs may also make it difficult to start the engine altogether. This happens because the engine isn’t getting access to enough power to get the cylinders moving. Remember, a vehicle’s engine relies on many different parts working in tandem together, and a single malfunctioning spark plug can throw a wrench in the entire system.

3. Lowered Fuel Economy

Another common sign of bad spark plugs is reduced fuel efficiency. As a malfunctioning spark plug misfires, the engine is unable to properly regulate the amount of gasoline burned in the cylinders, causing the vehicle to consume more fuel than it would otherwise.

How Often Should Your Change Spark Plugs?

As a general rule of thumb, drivers should consider changing spark plugs at least every 30,000 miles. With that said, it’s always best to follow the recommendations provided in your vehicle’s manual as some models may require new spark plugs sooner than others.
