I got this from ******** arizona today..

any thoughts on their response?

Lee,
Sorry, the rumors are true. In the last 12-18
months, Bosch has discontinued the production of
non-resistor type plugs for a variety of
applications, including your's. Bosch's reason
for doing so is because the average resistor plug
contains 100-200 Ohms of resistance while the
average wire set contains 5000. Bosch's
contention is that the resistance in the plugs is
so minimal compared to what is in the wires
anyway, it won't make a difference unless the
ignition system is having other problems. As
long as your ignition system is working properly,
Bosch believes everything should work fine.
I have even heard from some local mechanics that
other plug manufacturers such as Champion and NGK
are following suite and discontinuing the
non-resistor plugs. Unfortunately, there isn't
anything that we can do about this issue anyway
because H9DC, non-resistor plugs have not been
produced by Bosch in at least a year.

Best Regards,
Tom
