I'm pretty sure you are incorrect on this one... The 8 heat range plug is not a resistor plug... That's what the "R" in BR7EF is. I did some leg work for the OP with the research on plugs I did for my setup, he needs a B8EFS
B - 14mm thread diameter
8- Heat Range
EF - Tapered Seat .708" reach
S - Standard 2.5mm D Electrode
That's a breakdown of the NGK Part number
