What material is the original spark plug of the Sylphy Classic?
4 Answers
The original spark plug of the Sylphy Classic is an NGK platinum spark plug with a lifespan of approximately 40,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine, 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 engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for external debris such as leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order and secure the cover.
I've been driving the Nissan Sylphy Classic for several years, and to be honest, the spark plugs that come with the car are made of nickel alloy, which is quite common in many standard models and very cost-effective. Nickel alloy spark plugs typically last about 30,000 to 50,000 kilometers before needing replacement. Over time, they can accumulate carbon deposits, affecting ignition, and you might notice the engine doesn't start as smoothly. If you frequently drive in stop-and-go city traffic, your car's fuel consumption might be slightly higher. I recommend regularly checking the condition of the spark plugs to see if they're eroded or discolored. Delaying replacement could potentially harm the engine. Replacing them is simple and not expensive—nickel alloy spark plugs cost just over a hundred yuan. For more peace of mind, you could upgrade to platinum spark plugs, which have a longer lifespan and better performance. In short, the original spark plugs are nickel alloy, and with proper maintenance, your car will run smoothly. Don't wait too long to replace them.
Having worked in the automotive repair industry for many years, the Nissan Sunny Classic comes standard with nickel-alloy spark plugs, designed with cost control in mind. Nickel-alloy plugs have average durability and typically start to degrade around 30,000 kilometers, which can lead to delayed ignition or reduced power. For daily driving, it's important to pay attention to maintenance—for example, checking the spark plug temperature after parking; if it feels excessively hot, there might be an issue with the wiring. It's best to have a professional inspect the insulator and electrode gap every two years, or simply use a diagnostic tool to check for trouble codes. The standard nickel material is suitable for most drivers, but performance enthusiasts may consider upgrading to platinum spark plugs to reduce replacement frequency and save time and money. Remember to avoid using additives that could corrode the electrodes—keeping them clean improves ignition efficiency and ensures safe and reliable driving.
The factory-installed spark plugs in the Xuan Yi Classic are made of nickel alloy, which is quite common. Nickel alloy spark plugs are affordable and practical but have a shorter lifespan. It's best to replace them after about 30,000 kilometers, otherwise, they can affect fuel consumption. During inspection, check the tip of the spark plug; if there's significant carbon buildup, it's time for a replacement. I've driven this car and found no major issues—replacing them is convenient and the cost is reasonable. If you want to extend the service life, you can opt for platinum spark plugs, but the original nickel alloy ones are sufficient for daily driving as long as you maintain them on schedule.
