.. How many junk Bosch plugs have you replaced? Were they installed with a
torque wrench? Were they the correct plugs for the applications?
I began my career as a German auto tech in 1976 and I prefer Bosch. What
kind of experience is your opinion based upon?

My experience is based on both American engines and European and
Japanese....

Jeep straight six ones in particular...

I have seen a whole pile of older Jeep engines come to me for help
because no one can make them run.

When I look, see Bosch and say 'bad plugs', they 'all' say, but but but,
they are the expensive plugs and they are new!

As soon as I toss them out and drop Champion plugs in, the bad running
and missing at idle issues are gone.

Bosch 'used' to be good good plugs and they worked well in my past
experience for some of the higher compression engines, like VW and Volvo
but the Jeep 'thumper' engines just don't like them from what I have seen.

Poor choice of words. There are different varities of plugs, some of them
are designed to provide high output. If high output plugs are called for,
they must be used. I agree with you, if high output plugs are not called
for, they probably are not worth the added cost.

I once owned a GM car that needed something special in the plug. The catalog
at the parts house gave a listing for a plug that was missing a letter or
number somewhere in the middle, and this missing digit denoted that the
plugs were "high output". I attempted to use the plugs, and the car would
not run for crap. Since I was not able to understand all of the digits of
the part number, I missed the significance of a digit that was not on the
new plugs that I had in my hand.

I am not saying that the OP needs platinum plugs, I'm saying that there is
benefit in some motors for them.

That missing letter probably indicated no internal resistor.
