I don't believe that this is because platinum plugs are inherently bad.
They don't work right in many applications, just because somebody gets the
heat range wrong. That could be a bad listing, a half asleep parts jockey
or any number of factors. The only way to get the right heat range, unless
you are racing and have a radically modified engine, in which case you are
assumed to know what you are doing, heh, is to use OEM plugs. The type of
plug you need, is on the under hood label, in the owner's manual and in the
shop manual.

There is a big difference in performance, as Mike says, if you put the wrong
part in your engine.

And right after that, you might place a call to your local BBB and

This may or may not be related, but some aftermarket ignitions for
racing/high performance specify NOT to use platinum plugs. I do not know
the reason. As far as brands, I too have had problems with certain
brands of plugs in certain brands of engines, but some of these engines
were modifyed also. I have had the best luck with Autolite personally. I
had an old Mercury outboard that called for Champion plugs, but they
would foul out after a few weeks. I did a lot of trolling (not
newsgroups, lol) and the plugs would just crap out after a few weeks. A
simple cross reference to Autolite and I got a full summer of fishing
without any fouled plugs. OTOH, I have had engines that would run on
Champions and nothing else.

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.
