The Importance of Replacing Worn Spark Plugs

Spark plugs are an important part of your Kia’s engine. While they don’t need changing as often as the oil, they still need regular maintenance and replacement. Fortunately, Suntrup Kia South has skilled technicians to help with all your Kia’s maintenance needs whether you live in St. Louis, Missouri, or nearby Kirkwood or Webster Groves. While Kia and spark plug manufacturers have recommended spark plug intervals, sometimes spark plugs wear out prematurely. Here are some of the signs that your spark plugs may need changing, the problems you may experience if you don’t change them, and why you should bring your car into Suntrup Kia South for the service.

How Spark Plugs Work

Spark plugs have been components of an internal combustion gasoline engine since these engines were invented. Their main job is to provide an electrical source, or spark, to ignite the gasoline in the combustion chamber to provide power. The process is lightning-fast and controlled by precise timing so that the engine gets the most power and efficiency at the same time.


What Happens When Spark Plugs Wear Down

Most spark plugs have a specific-sized gap in their electrode located at their top. As the plugs wear down, this gap widens and your Kia’s engine loses some of that precise efficiency. Also, some types of gasoline and fuel additives can contaminate that electrode and cause trouble. When your Kia’s spark plugs are worn or contaminated, you may notice more sluggishness during acceleration and a gas mileage decrease. Your car could be more difficult to start and you may also feel an uneven idle. While your car’s engine control module, otherwise known as its computer, compensates for some wear, at first, it may not be able to do so when the problem is severe.

How Suntrup Kia South Can Help

While you can change your spark plugs yourself, you may want to have a professional do the job. Some Kia engines have deep-set spark plugs that are difficult to remove without special tools. Also, your car’s engine is specifically fine-tuned to run on a specific type of manufacturer-approved part. Since we are Kia experts, we are able to easily supply that exact type of plug or any other recommended spark plug. If you are in St. Louis, Kirkwood, or Webster Groves area, and your car is not running the way you like, or you simply need to know your Kia’s recommended service schedule, then stop on by Suntrup Kia South.
