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. ----- Original Message ----- From: Christopher Hoffman Sent: Wednesday, March 05, 2003 9:48 PM To: mailing-list@xxxxxxxxxxxxxxxx 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
