Here are the NGK spark plug guides for us.

Using the chart attached below, we see that the NGK BPR6ES spark plug (for example) refers to:

B - 14mm Thread Size and 13/16" Hex Size

P - Projected Tip

R - Resistor Type

6 - Heat Rating (2 = hot, 12 = cold)

E - 19mm Thread Reach

S - Standard 2.5mm center electrode
