ITYM "right side up." A huge gap isn't generally a problem except under
heavy load. No gap results in no combustion.

Who can say? but in my experience Autolite and Bosch are decent,
Champion decent but don't clean after being fouled, and I pretty much
stay away from "platinum" anything because all my personal vehicles are
fairly aged.

Autolites are what I use.I have never had any problems with them yet.

in my experience, the only plug out there's that's really got its act
together is ngk. quality electrodes, even for the base varieties, good
insulators, good self-cleaning, and the body is decently corrosion
resistant. i've had ngk's work even when they electrodes have been
burned down to little stubs of melted meteorite.

denso still use the detachable plug tops that can cause all kinds of
problems, but are otherwise good.

bosch, while they're fine when they work, have a nasty habit of simply
not working when you go to start the car one morning. i can't forgive
that, and it's happened to me a number of times over the years.

champion have never let me down, but they're do so great in the
corrosion dept, and pretty cheaply made so they don't last and need
frequent replacement.

autolite? utter carp.

delco? like autolite only not as good.


regarding "platinum" or other fine electrode materials, there is no
reason to not use these in an older vehicle. indeed, there are
benefits, particularly on carburetted systems, because they're generally
able to fire in a broader range of mixtures, temperatures and with a
broader range of voltages than traditional plugs. basically, the finer
the electrode, the higher the spark ignition efficacy - which is what
you want in a plug. the only reason you don't make traditional plugs
with fine electrodes is that the cheaper materials can't cope, not that
they wouldn't benefit from having them.

i love this - perpetuation of myths about "german cars need german
plugs" , with the equivalent for japanese and domestic, is utterly baseless.

You make a good point. Maybe he NEEDS to have his engine mounted
upside down. He'll have to pay for it, but it shoudln't be too much.

I resolve these issues by buying NGK or ND plugs. Since I have Jap cars
anyway.

I used them in a Chrysler, too.

IIRC, in the early days, all spark plugs used to be imported (probably
from Germany?)- that is why they were the only part in the (US-built)
car with metric threads. Or is that an urban myth?

The first commercially viable ones were supposedly made
by Bosch.
