That missing letter probably indicated no internal resistor.

"R" innit?

I never tried to keep count. If I had to guess I'd say I have had around
50-60 vehicles that didn't run right with Bosh plugs.

Don't know as I wasn't the one that installed them. That said, why do you
think a torque wrench would make a difference ? I personally never use a
torque wrench on spark plugs and have never had a problem in over 30 years.


Were they the correct plugs for the applications?


I had no way of checking that.


> I began my career as a German auto tech in 1976 and I prefer Bosch.


You are the ONLY tech I have run into that actually likes Bosh plugs.
Everyone else has had problems with Bosh plugs at one time or another.

I have been working on cars for over 30 years, most of that
professionally. I have worked in dealerships and independent shops. My
experience with Bosh is that the customer comes in complaining about the way
their car runs, check engine light may or may not be on and they just had a
tune up done 1 week to 1 month ago. I bring the car in to look it over and
all the tune up parts are new. Remove Bosh plugs and replace with any other
brand and car runs great. This gets to be a common problem so anytime I get
a vehicle with a driveability problem that has Bosh plugs installed I
replace the Bosh plugs first. Everytime the Bosh plugs are replaced with
another brand driveablity problems are gone as well. I also can say from
experience that some cars appear to run OK with Bosh plugs. I have run
across a few vehicles that had Bosh plugs installed that ran fine. However,
every tech I have talked to has had a similiar ( read bad ) experience with
Bosh plugs. Oh, I looked at all the Bosh plugs that I replaced because of
problems and you could see nothing wrong with the plugs, they all looked
like new. Yet a new set of plugs, anything but Bosh, cured the problems.
That's my experience and that's why I won't use anything Bosh makes.
