If I were not using nitrous, I'd use Autolite #25s. Since I'm on the spray, I use the one heat range colder Autolite #24s.

Copper core plugs rule...

As soon as I can get the car put together, I'll be running copper Autolite 3924's. Don't run Bosch, and NGK are good plugs but I tend to think of them as import plugs. Autolites, Motorcraft, or Champions are the brands I run in my vehicles.

NGK

They are hard to foul unlike the autolites I had and cheap from summit.

 

[N8Miller]

autolite 3923s.

Autolites and Motorcraft are one the same just for some fyi. Made by same company.
And for reference I think I am using awsf 12's or agsf -12's on mine, being that its supercharged, they are gapped at .035-.038. They work great too.
