MH asked me to start this thread concerning the new (not available yet) spark plug. He knows I have a camera and older sleds as well as the new 12 PRO.
Here are the pictures, I can't see any difference but I know that doesn't mean anything with spark plugs. Below are side by side pics of the older standard NGK BPR9ES, and the new NGK GR9A-EG.
I have not been able to find any technical data on the differences, except that the plug is considered a racing plug. Here ya go MH, I suspect you know something about these spark plugs.
