What is the complete cross-reference table for NGK spark plug models?
2 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.
The complete cross-reference table for NGK spark plug models isn't actually a simple chart, as there are too many model numbers like BKR6E-11 or LFR6AIX-11 which represent the spark plug's heat range, electrode type and dimensions. Typically, the official website provides online tools or downloadable PDFs - you can visit NGK's international website and input your vehicle's year, make and model, then it will automatically match the recommended spark plug. I often help friends look this up myself, as using the cross-reference table ensures stable engine ignition after replacement, avoiding hard starts or high fuel consumption. Choosing the correct heat range is crucial - smaller heat range numbers indicate slower heat dissipation (suitable for high-performance vehicles), while larger numbers mean faster heat dissipation (better for regular cars). Remember not to rely solely on memorized model numbers, as data differs between older and newer models - the latest version is more reliable. I recommend bookmarking the official website link for convenient future reference.
