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.

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.

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.

Never heard of "high power plugs", care to explain what they are and when
the are required ?


>

I have never seen an engine that REQUIRED plantinum plugs. Platinum plugs
are usually used in applications where the plugs are a bitch to replace. The
are generally good for 60,000 - 100,000 miles. I have seen regular plugs
used in place of platinums quite often and they perform no differently
except they don't last as long.

Never heard of "high power plugs", care to explain what they are and when
the are required ?

I have never seen an engine that REQUIRED plantinum plugs. Platinum plugs
are usually used in applications where the plugs are a bitch to replace. The
are generally good for 60,000 - 100,000 miles. I have seen regular plugs
used in place of platinums quite often and they perform no differently
except they don't last as long.

Before plat was common Bosch made Silver plugs. The idea is that plat (or
silver) LASTS LONGER THAN THE PLAIN ONES, oops keeping the gap for longer,
as required by smog laws. So instead of changing plugs at normal intervals,
Plats make cleaner air longer for those who don't do proper maintenence.
When you get to dual-fire style coils, like mid 90s GM products, one plug
fires + while the other fires -, so a dual plat is called for.

Platinum plugs resist wear better. That's it.

They are not 'high power' (whatever that means).

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.
