How Long Can Iridium Spark Plugs Last?

[LeLeonardo]

Iridium spark plugs can last approximately 60,000 to 80,000 kilometers. The function of spark plugs is to introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Spark plugs are installed on the side or top of the engine and require a working voltage of at least 10,000 volts. Common spark plug faults include: 1. Spark plug leakage; 2. Black deposits on the electrode; 3. Cracked insulator tip; 4. Oil fouling on the spark plug; 5. Spark plug erosion; 6. Excessive spark plug gap.
