[StGabriella]

Baojun 530 spark plug replacement cycle: Under normal maintenance conditions, replace after driving 40,000 to 60,000 kilometers. However, it may vary depending on the brand and engine. It is recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Spark plug working principle: The spark plug's ground electrode is connected to the metal shell and is threaded into the engine block through the cylinder head. The insulator mainly serves to isolate the metal shell and the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it breaks down the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.
