Are you guys saying that the NGK BPMR6F and the Champion RDJ7Y spark plug are the same physically?
If so, then my BME and Brison plugs can be used interchangeably.

Have you tried the NGK BPMR6f? It's allot cheaper and I have been not able to tell any performance difference between the two. The NGK fits the cap.
