Installation Tips
1. Before removing the old spark plug, please clean the surrounding area to avoid dirt falling into the combustion chamber when the spark plug is taken out
2. Gentle action is required when removing the high-voltage wire connector, and avoid shaking the spark plug vigorously, so as not to damage the performance of the spark plug
3. Disassembled spark plugs one by one.
4. Do not skew when installing the spark plug.
5. Use a torque wrench to tighten according to the specified torque. Don't use electric tools.
6. The spark plug should be kept clean, dry, and free of oil, otherwise it may cause faults such as electric leakage.
