OEM Kia Soul Spark Plugs

Keep Your Kia Soul Running Strong with Quality Spark Plugs

The Horne Kia parts team knows what it takes to keep your vehicle running great. Spark plugs ignite the air-fuel mixture inside your engine's combustion chambers. These small but critical components create electrical sparks that start the combustion process powering your vehicle. Your Kia Soul depends on properly functioning spark plugs to deliver smooth acceleration, fuel efficiency, and reliable starting in all weather conditions.

Understanding Spark Plug Function

Each spark plug screws into the cylinder head with its electrode extending into the combustion chamber. When ignition coils send high-voltage electricity to the plug, current jumps across a small gap between electrodes, creating a spark. This spark ignites the compressed fuel-air mixture at precisely the right moment. The Kia Sportage and Kia Telluride use similar spark plug technology to ensure efficient combustion in their engines.

Why Spark Plugs Deteriorate

Electrodes gradually erode from millions of sparking events, widening the gap and weakening spark intensity. Carbon deposits accumulate on the insulator and electrodes, interfering with proper spark formation. Oil or coolant leaks contaminate plugs, causing misfires. Temperature extremes and engine stress accelerate wear. Aftermarket spark plugs often use inferior metals that cannot withstand the heat and electrical stress in modern engines. These cheap alternatives lack the precise gap dimensions and heat range specifications of genuine Kia plugs, resulting in poor performance and potential damage to your ignition system that affects fuel economy and emissions.

When to Replace Your Spark Plugs

Replace spark plugs if your engine runs rough, hesitates during acceleration, or struggles to start. Poor fuel economy and a check engine light indicate potential plug problems. Most spark plugs last between 30,000 and 100,000 miles depending on the plug type and driving conditions. Follow your owner's manual for specific replacement intervals.
