Grrrrr. Do non-resistor spark plugs still exist?

[S-Class Guru]

What a pain!
I know to use only non-resistor Bosch plugs in my '91 103 motor.
So, I check Fastlane - not available, back-ordered.
I check another mail house - same story.
I check a 3rd place in New Jersey - THEY HAVE THEM.

So, I order them, and the next day they arrive, shipped from a warehouse
10 miles away from me in Dallas. BUT THEY ARE THE RESISTOR TYPE - WRONG PART NUMBER.
Well, I pay $8 to ship them to New Jersey on an RMA.

A few days later, I check the 2nd supplier, in Atlanta - THEY HAVE THEM.
Well, you know the rest - they arrive the next day from the same warehouse down the street from me. WRONG AGAIN.
So, now I gotta ship them out if state again, for another $8 lost.

Oh me, sometimes dealer 4X markup doesn't seem so bad.


I wonder if we are going to be SOL with the older non-resistor engines?
Will the resistor plugs work for at least a short while?
Are poor idle, and fouling, and increased emissions, and reduced fuel mileage
the only drawbacks; or can the ignition system suffer over the longterm using resistor plugs?

grrrr again,
