How long does a single platinum spark plug generally last?

[DiAniyah]

The service life of a single platinum spark plug is 60,000-90,000 kilometers. Methods to determine platinum spark plug condition: Check if cold starts are smooth. If there is severe shaking during idling, the spark plug may be faulty. Observe engine vibration - if the engine exhibits intermittent or continuous shaking, the spark plug may be problematic. Inspect the spark plug color - severe erosion, blistering at the tip, black streaks, cracks, or melted electrodes indicate a damaged spark plug. Factors affecting platinum spark plug performance: Excessive carbon buildup on the spark plug itself, poor contact in high-voltage wires or ignition coils, excessive resistance in high-voltage wires, prolonged operation of ignition coils leading to weakened high-voltage electricity - these factors directly impact spark plug lifespan.
