Thread: Spark PLugs

Tweet

what is the favorite spark plug to run, Bosh,motorcraft, autolight, splitfire..?
im going to be running JBA 8mm spiral wires with a HEI dist in my 429 , just wondering what people use

i use autocraft and have found them to be great.

Probably going to get as many opinions on this as there are plug brands.... In the drag cars, we run NGK, on the steet, we run Autolites... But the lawn mower and snowblower still run best on Champions!!!!

Snowblowers yes, Fords no. I have never gotten Champion or A/C plugs to work in a Ford worth a darned.

Yup, know what ya mean!!! The NGK's work great in the drag cars, both are on E-90...Autolite's wouldn't cut it, or maybe we didn't hit the right number. Anyway, I know an NGK rep, he got us a good number for the big blocks. On the other hand, can't get the NGK's to live in a street engine... Again, could just be not having the right numbers???? But the Autolites have always done great in the Windsor's and Clevelands on the street...

i'm kinnda old thinking i guess but i usally ac in gm.. motorcraft in ford..champion in a mopar..bosh and ngk in german english and japanese..but im not above trying anything ..plus i've been out here in the woods for along time

ok, so what should i put in my 429, going to be upgraded with jba headers, edelbrock cam 750 carb , intake ,true roller timing , procomp hei dist and jba 8mm wires, will be the weekend warrior, not a daily driver

Actually Champions run best in my 68 Chevy 350. Short reach plugs (3/8") that acually come in single packs. Last time I bought some the guy at the auto parts store asked me if they were for my lawn mower.

I have not tried AC Delco's (use them in my 57 Olds) but I have use Denso's and Autolites, but like neither as much as the Champion's.
