Once ya get rid of these then try reading a decent plug.
If your running a stock car, with no mods., they might work for over a 100
miles.
I farted around with them several times in hot rodded engines and the always
were prolemmatic.
Forget all the hype and just get a decent conventional plug.  For the $ of
the trick ones you can afford several sets of good plugs.
If seriuos about tuning index em.
Bone white generally indicates lean, too hot of plug.  But, I've had a
properly tuned engine do that with several different heat ranges of
Rapidfires.
ACs or Autolites are usually the best.
Rotaries use NGK.
MB Porsche like Bosch
