Surprised no one has brought up plug indexing here...that's an old school method of "improving" performance by positioning (via rotating) the sparkplug such that the gap is facing the center of combustion chamber rather than away from it.
So does anyone have any insight as to which plug is the most resistant when considering quenching...or do the plugs referred to previously offer a charge/spark hot enough to take it out of consideration.
Good catch! So much from my reading skills....though it was near the end of a different topic ;-)MexicoMike brought it up, two hours ago.
They may be good for some applications but I bought a Mercedes 190 a few years ago really cheap because nobody could fix the intermittent warm start problem. It always started cold but when it was anything but cold -you couldn't count on it. After a lot of time and a bunch spent on parts I finally took out the nice clean e3 plugs that were in it and put in a set of Bosch's. Problem solved.
Never tried them again after that.

Any curiosity is gone now and will stick with the purchased Denso's.

Best price for those I could find in Australia was here...fwiw.

A while back I ask a guy well known in the USA about what spark plugs he recommended having owned and works on (his day job) this particular bike brand for decades.
I was surprised to get back, plain old base line plugs, BP6ES in this case.
That made me curious enough to google the subject and a good deal suggested exotic tipped spark plugs were mostly aimed at longevity in cars more than performance.
I ask the dude at a large parts store (He could have tried to talk me out of ES's) and in our chat mentioned unless he was mistaken, top fuel dragsters were using copper plugs last time he was at the strip.
100,000 road miles or 20 fast race laps...
My question is what is optimal gapping, and how can you evaluate?
