How often should the original spark plugs of the City be replaced?
2 Answers
Honda City spark plugs should be replaced every 100,000 kilometers. The model of the City spark plug is NGK-IZFR6K136774, an iridium spark plug. The better the material of the spark plug, the longer its service life. Additionally, the model of the spark plug must match the engine model. Below are the steps for replacing the spark plugs of the Honda City: 1. Disconnect the ignition coil wiring harness plug, remove the ignition coil fixing bolts; inspect the spark plug (check if the terminal is damaged, if the insulator is punctured, if the electrode is worn, etc.). 2. Select the appropriate tools, assemble the tools, remove the spark plugs, and take them out one by one; cover the spark plug hole on the cylinder with a cleaning cloth to prevent objects from entering the cylinder. 3. Align the ignition coil with the spark plug, install it in place, and use tools to screw in the bolts; clean the measuring tool, measure the spark plug gap, and evaluate the spark plug. 4. Check the new spark plug for any appearance issues, insert the spark plug into a special sleeve, screw it into the spark plug hole using a digital torque wrench, tighten the spark plug, turn off the ignition switch, open the engine hood, and install the three-piece set. 5. Use a digital torque wrench to tighten. Start the vehicle, clear any faults, and tidy up the workstation.
I've been driving my Honda City for over three years, and I pay special attention to the original spark plugs. Generally, it's recommended to replace them every 100,000 kilometers, but in actual driving conditions like mine, where I frequently encounter city traffic jams, the wear and tear can be faster. It might be necessary to pay attention as early as 70,000 to 80,000 kilometers. Last time, at 80,000 kilometers, I noticed delayed starts and an unexplained increase in fuel consumption. Upon inspection, it was found that the spark plugs had carbon buildup. After replacing them, the engine response became much smoother. Spark plugs are crucial to the ignition system; when they age, they can lead to incomplete combustion, increasing exhaust pollution and fuel wastage. Now, I've made it a habit to have the mechanic check the electrode gap during every 50,000-kilometer maintenance to ensure it's in optimal condition. Choosing original equipment manufacturer (OEM) parts ensures compatibility—don't just switch to cheap alternatives, as they can affect performance. In short, adjust based on the manual's recommendations and actual vehicle conditions, with safety as the top priority.
