Spark Plugs ignite the fuel-air mixture in the engine cylinders, creating combustion that provides the energy to move your Kia. These plugs wear out with age and can also be damaged by problems with your engine. Check out some of these signs you need to visit us to have us replace your car’s spark plugs.

Signs You Need Your Spark Plugs Replaced at Your Kia Dealership
Carbon Buildup
If you notice carbon buildup on the spark plugs, it’s a sign your engine can be running fuel-rich. Combustion occurs when air and fuel, mixed in a precise ratio, are compressed and then ignited by a spark plug. If the mixture isn’t the right ratio, it can become fuel-rich. A fuel-rich engine can lead to the buildup of carbon on the spark plugs.
Carbon attaches to the spark plugs and it may make the spark plugs work harder as a result, and they may wear out faster. In addition, the buildup of carbon can cause engine misfire issues. Our technicians will replace the damaged plugs and get the performance of your car’s engine back up and running great.
Damaged Ignition Coils
A spark plug screws into the cylinder head, and can be connected to ignition coils. Ignition coils wear out due to age and while the time for replacement can vary, generally they can last around 100,000 miles. We’ll replace any damaged coils and test and replace any damaged spark plugs.
Oily Spark Plugs
Another sign that your vehicle needs its spark plugs replaced is if you find oily spark plugs. Worn parts in your vehicle can allow oil to get to the spark plugs and affect the engine performance of your car, causing things like misfires and can even damage the engine if it gets too severe. We’ll replace the damaged plugs and install new seals to help fix this issue.
