What is the corresponding model for motorcycle spark plug D8TC?

The corresponding model for motorcycle spark plug D8TC is NGK D8EA. The function of a spark plug is to generate a high-voltage electric spark to ignite the compressed combustible mixture. It ensures the normal operation of the engine, and without it, the vehicle cannot start. If the spark plug is properly maintained, the vehicle will be very fuel-efficient and quiet, with no noise, which is beneficial for motorcycles. Spark plug maintenance precautions: Always keep the spark plug insulator clean and dry. During normal use, dust, oil, and other deposits may accumulate on the spark plug insulator. These deposits form external leakage paths, which can affect the normal sparking of the plug. When inspecting the engine or performing other operations, be careful not to bump the spark plug insulator to avoid damage due to force, which could affect the normal operation of the spark plug. When connecting or disconnecting the high-voltage wire, be gentle and avoid excessive force or shaking the spark plug insulator to prevent damaging the spark plug's seal or causing the spark plug to fail. New spark plugs or those removed for cleaning and inspection should not be dropped or thrown to avoid damaging the insulator.
When repairing motorcycles, I often use the spark plug model D8TC, which is a standard specification typically corresponding to NGK's DR8ES or Bosch's W8AC. With a heat range of 8, it suits most domestic motorcycles like the Honda CG125. Choosing the wrong model can lead to unstable ignition and increased fuel consumption. For daily riding, inspect the spark plug electrode gap every 10,000 kilometers, maintaining it at around 0.7mm for optimal performance. During replacement, ensure the threads match a 12mm diameter and 18.5mm length. Remember to use a torque wrench for gentle tightening to prevent damage to the cylinder head. This model is durable and affordable but prone to overheating at high RPMs, so regular cleaning and pairing with a high-quality ignition coil are recommended. Safe riding starts with attention to detail—don't overlook small components.
