Hello raptor,
I addressed that statement in post #51 of this thread and Eric covered it in post #53
The same can be said for any other part in the Turbine, if a bearing goes for example you are done for the day also...
I believe that the ceramic ignitor will not show up to be a weak link in this system.
BTW maybe cars should still be using points instead of electronic ignitions, or carburetors instead of fuel injection....
