Spark plugs Sonata + Azira

The spark plugs (ignition candle or spark plug) for my Hyundai Sonata and Hyundai Azera are the small part that generates a high-voltage electric spark inside the combustion chamber to ignite the fuel-air mixture, resulting in combustion that drives the engine. The importance of the spark plug lies in being the primary responsible for starting the combustion process at the correct timing for each cylinder, ensuring engine power, throttle response, fuel efficiency, and reduced harmful emissions. The high-quality heat-resistant insulating material, the corrosion-resistant metal electrode, and the precise gap design ensure a strong, steady spark and a long lifespan. Replacing the damaged or worn spark plug, which has become weak or intermittent in its spark, restores engine power and smooth operation, and any vibration, difficulty starting, or increased fuel consumption immediately disappears, so your car runs efficiently and energetically. **Specifications** - Compatible models: Hyundai Sonata, Hyundai Azera - Part name: Spark plug - Storage number (SKU): 18841-11051
