• Working environment: The job involves enduring high pressure, high temperatures (thousands of volts of high voltage and intense combustion), as well as chemical corrosion.
• Regular replacement: As a consumable part, it needs to be replaced regularly (approximately every 20,000-30,000 kilometers for nickel alloy, and approximately every 60,000-80,000 kilometers for iridium).
• Carbon buildup impact: Carbon buildup or oil stains can lead to electrical leakage, causing difficulties in starting, unstable idling, and reduced power output.
• Fault Symptoms: When the spark plug ages, the vehicle usually exhibits symptoms such as acceleration hesitation, increased fuel consumption, and cylinder misfiring vibration.
• Multiple spark plugs per cylinder: Some high-performance automotive engines adopt a design with multiple spark plugs per cylinder to enhance combustion efficiency.
