How many kilometers does a GAC Honda spark plug need to be replaced?
2 Answers
GAC Honda uses NGK iridium-platinum spark plugs, which have a replacement cycle of 60,000 to 80,000 kilometers. Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. You can refer to the following standards for maintenance and 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 plugs are an important component of the gasoline engine ignition system. They introduce high voltage into the combustion chamber and generate sparks by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. The main types of spark plugs include: standard spark plugs, insulator-protruding spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs.
I've been driving GAC Honda cars for many years. The recommended mileage for spark plug replacement is generally around 80,000 to 100,000 kilometers, depending on the specific model like Accord or Fit, as clearly stated in the manual. However, in actual driving conditions, if you frequently drive in congested urban areas with frequent engine start-stop cycles, the wear on spark plugs can accelerate, possibly requiring replacement as early as 60,000 kilometers. I once experienced engine shaking at idle, and after inspection, it was found that aged spark plugs caused poor ignition. After replacement, the power returned to smooth operation. During regular maintenance, it's advisable to have the technician check the spark plug condition. If the electrode gap is too wide, it can affect fuel efficiency and increase carbon buildup issues. Delaying replacement may lead to increased fuel consumption or the risk of sudden engine stalling. Based on my experience, combining the manual's requirements with personal driving habits is the most reliable approach.
