How often should the spark plugs of an Accord be replaced?
2 Answers
The spark plugs of an Accord are typically replaced every 30,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. The following standards can be referenced 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. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires according to the firing order, and then secure the cover.
I've been repairing cars for many years, and the replacement interval for Accord's spark plugs mainly depends on the material you use. Ordinary nickel alloy ones typically need replacement after about 20,000 to 30,000 kilometers, while platinum ones can last 40,000 to 50,000 kilometers. The factory-equipped iridium spark plugs nowadays are even more durable, generally lasting around 100,000 kilometers. However, actual usage depends on driving habits. If you frequently encounter city traffic jams or enjoy sudden acceleration, carbon buildup on the spark plugs will increase, possibly requiring replacement as early as 70,000 to 80,000 kilometers. When replacing, make sure to choose the correct model—original factory or reputable brands like NGK are the safest. If you're doing it yourself, ensure they're tightened properly to prevent air leaks, which could affect engine ignition. It's advisable to check the spark plugs' condition every 30,000 to 40,000 kilometers. If you notice shaking or increased fuel consumption, address it immediately.
