I agree that Autolites
don't seem to fouls as easily. Another plug that works quite well in a car
that tends to run a little rich at times are AC Delco Rapid Fires. (Don't laugh,
they do a good job).

O. K. My thoughts on Champion plugs. They foul very easily on Mopars! For
that mater so did the Mopar plugs! When I bought my 71 New Yorker and then
latter Imperials I have found over and over again that Champion and Mopar
plugs will foul faster than AC, Autolite, NGK, or "Nips". This is also true in
my snowmobiles. Boch plugs also work well. If everything on the car was
correct I could run anything. I have found the Champs and Mopar plugs just
foul faster when something is wrong. I even mixed plugs and the champs and
Mopar plugs always fouled first when I had rich mixtures. Do what works for
you, but putting plugs in a 71 New Yorker and even the 73-72 Imperial was
always a pain on at least two of them. Good luck! De Vere 1960-1975 with
mostly Autolite plugs because they are cheap and do not foul easily.

Subject: Re: IML: spark plug
advice
Michael, I'm not sure what I said that made you take such
apparent personal
offense at my trying to help out a new member by
recommending a product that
works well, but nothing so evidently
irritating was intended. Just a hearty
endorsement.
My personal
experience, and that of numerous others on this list and
elsewhere, is
that Mopars (especially of this vintage) do not like
Champions, and that
switching to Autolites in itself helps cure pinging,
fouling and numerous
other unpleasantries of poorly running older cars.
The original owner
of my '67 ran Champions religiously, and when I bought
the car it had
anti-foulers on five of the plugs! Since this seemed like
wearing a suit
made entirely of BandAids, I sought a real solution to this
and the car's
seemingly uncurable pinging. A dear friend introduced me to
his honest,
old-timer mechanic, a man named Gene who passed away at 84
several years
ago. When my friend asked Gene if he knew anything about '67
Imperials,
Gene said "Sure, a little. Bought one new and still have it!"
Gene got me
hooked on the Autolites. In one service visit, that change
alone
contributed so much to the car running well that I never looked at
a
Champion again, and have endorsed them to friends and acquaintances
without
a single instance of anything less than happiness with the
result.
I run Autolites on every pre-2000 Mopar I own (I have yet to
pull a
factory-installed plug on my new cars, but my '93 Jeep loved 'em
too), from
a '63 Dart to a '78 NYB. Every one of these runs well, there
is no pinging,
the plugs never foul, and the NYB just passed CA's Smog
Check with flying
colors (and with an engine that was not even available
in CA when new).
Combined with the support of all the other IMLers who
have had similar good
experiences with Autolites, I felt confident in
recommending them.
And since I didn't originally interpret the new
member's comment that his
car was using fuel faster than he could put it
in as meaning a carb leak (I
read it as a hyperbole for poor as mileage),
I thought I'd try to offer the
most overlooked low-cost things to get out
of the way first.
By the way, I run NGKs and NDs in my Japanese cars,
since that's what works
best for me in those. I'm not a mouthpiece for
Autolites, just happy to
share good experiences with
others.
Cheers indeed,
Chris in LA
