Re: What brand of spark plug?
I only run Bosch Platinum or NGK.
Autolite is absolute trash. Champion isn't far behind. AC Delco is decent. Just my $0.02.

Re: What brand of spark plug?
Anything but Champions. I use AC R44ts or R45ts if it uses the tappered seats. About 71 up. On the flat seat with gasket I use R44s or R45s.

Re: What brand of spark plug?
I have used Autolites....After 30 years,I've never had any trouble.
I have bought one set of AC Delco....One died after about a month, Replaced it with one of the old Autolites I removed. That was my first and last set of AC's

Re: What brand of spark plug?
AC Delco. I even had Motorcrafts *cough* in it once and they worked fine too. Only plugs I ever had trouble with were Champions -- that was a long time ago and I have not tried them since. Burn me once....

Re: What brand of spark plug?
GMCDUDE what acan of worms you have opened !! haha
Choice of spark plugs is like choice of color. At my place we run AC Delco in GM's Motorcraft in F^&*'s, and Champion in Chrysler. The asian will mostly get NGK. I personally have AC DELCO in both of my old Chevy's amd will use nothing else |

Re: What brand of spark plug?
NGK's are supposed to be really good. i run those on my vintage honda motorcycles. many cars can use other brands of plugs, but it is good insurance to stick close to the factory.
Chrysler: Champion Ford: Autolite GM: AC Delco etc, etc, etc..... |

Re: What brand of spark plug?
NGK Irridiums in everything I own.
Tried Bosch had nothing but problems, Champion truck plugs in the 454 did OK, but the NGK's sing, no start problems at all. Love those things, except the price, but they work. |
