How often should the spark plugs of a 1.6L New Sagitar be replaced?

[VanDominic]

Under normal circumstances, the service life of a 1.6L New Sagitar's standard resistor spark plug is 20,000 kilometers, platinum spark plugs last up to 40,000 kilometers, while iridium spark plugs can reach 60,000 to 80,000 kilometers. Actual conditions may vary. Here is relevant information about spark plugs: 1. Introduction: The spark plug is a key component in a car engine's ignition system. Its function is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder, creating a spark across the electrode gap to ignite the air-fuel mixture. Currently, common types of spark plugs include resistor spark plugs, platinum spark plugs, and iridium spark plugs. 2. How to determine if spark plugs need replacement: Remove the spark plugs and observe the color of deposits, the electrode gap, and whether there is air leakage between the ceramic insulator and metal shell. If the car has difficulty starting when cold, noticeable jerking during driving, idle vibration, or reduced engine acceleration performance, the spark plugs should be inspected promptly.
