Are there different types of spark plugs for the Teana?

[DeIsabella]

Teana spark plugs do not have different types; they all use the original NGK iridium-platinum spark plug, model DILKAR6A11. The main types of spark plugs are: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the center 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 center electrode, it ionizes the medium between the center electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder. Spark plug replacement intervals: Under normal maintenance conditions, they should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the owner's manual. The following standards can be used as a reference for maintenance replacement: Platinum spark plugs should be replaced every 40,000 km, ordinary nickel alloy spark plugs every 20,000 km, and iridium spark plugs every 60,000 to 80,000 km.
