OEM Kia Spark Plugs For All Models

Maintain Ignition with Quality Spark Plugs

Big box stores and chains might be cheaper, but they can't guarantee the parts you're buying are genuine. Spark plugs ignite the air-fuel mixture in your Kia's engine cylinders, creating the combustion that powers your vehicle. These threaded components deliver electrical current from the ignition system to create a spark at precisely the right moment. Vehicles like the Kia K5 and Kia Carnival require properly functioning spark plugs for smooth operation and fuel efficiency.

Create Combustion for Power

Spark plugs receive high voltage electricity from ignition coils and create an arc across their electrode gap. This spark ignites the compressed air-fuel mixture in the combustion chamber. The timing of each spark is precisely controlled by the engine computer for maximum efficiency and power. Multiple plugs fire in sequence across all cylinders to create smooth, continuous power. The spark must be strong enough to ignite the mixture reliably under all operating conditions.

Recognize Spark Plug Wear

Electrodes erode gradually from repeated electrical arcing over thousands of combustion cycles. Gap spacing increases as electrodes wear, weakening spark strength. Carbon deposits and oil fouling coat electrodes, preventing proper spark formation. Misfires occur when worn plugs can't ignite the mixture reliably, causing rough idle and poor acceleration. Most spark plugs need replacement every 30,000 to 100,000 miles depending on plug type. Ignition coils work with spark plugs and should be inspected during plug replacement.

Genuine Kia Spark Plug Benefits

Factory Kia spark plugs use proper heat range and electrode materials specified for your engine's compression ratio and operating conditions. They provide reliable ignition without premature wear or fouling. Aftermarket plugs may use incorrect heat ranges causing pre-ignition or fouling problems.
