I have been using Bosch plugs for over 30 years as a professional mechanic,
and have seen one bad new plug. I have seen quite a few bad new Champions,
though.

Yea. If you've ever sat a Champion beside an Autolite, the Champion
looks cheap. Pot metal instead of forged cheap.

I'm running Champs right now but will switch to Autolite in a few
more miles.

I have had the same bad experience with Bosh plugs that you have, Mke, and
not just with jeeps. Just replace the Bosh plugs with ANY other brand and
the vehicle runs well again.

Let me clarify the above massage you quoted. ALL Bosh plugs are JUNK,
platinum or regular.

Now, the following pertains to good quality spark plugs. The only
difference between a regular and a platinum spark plug is that the platinum
spark plug will last longer. There will be no difference in performance
between the two.

Not true IF high power plugs are required.

I agree that platinum plugs won't hurt, and they could help. But if they are
REQUIRED then they have to be used.

Having said that, I do not believe they are required.
