What is the complete cross-reference table for NGK spark plug models?
1 Answers
Here is the complete cross-reference table for NGK spark plug models: 1. The first letter in the NGK spark plug model represents the thread diameter of the spark plug. For example, A represents an 18mm thread, B represents a 14mm thread, C represents a 10mm thread, D represents a 12mm thread, E represents an 8mm thread, BC represents a 14mm thread, BK represents a 14mm thread, DC represents a 12mm thread, etc. 2. The second letter in the NGK spark plug model represents the resistance of the spark plug. For example, R represents a built-in resistor type, and Z represents a wound wire resistor type. 3. The numbers represent the heat range. The higher the number, the better the cooling performance. 4. Taking the BKR6E spark plug as an example, BK represents a 14mm thread diameter, R represents a built-in resistor type, 6 represents the heat value, and E represents a 19mm thread engagement length.
