With a much more limited selection of plugs available for rotary
applications, I have seen this happen with most of the cheaper alternatives
to the stock NGK's.  Autolite's rotary plugs in particular have a nasty
habit of losing the center electrode into the engine, trashing an apex seal
and then that entire rotor housing.  I've never heard of it happening with
the NGK's though, and because I've been happy with the quality of those
plugs in my RX-7, I use them in my other cars as well whenever possible.
