Autolite Plug (3 ranges colder)

I am currently running Autolite 103's. I would like to run an Autolite Plug 3 heat ranges colder than stock. Can someone please help me out with part numbers?

Thanks,
Craig

I think they are 3 heat ranges colder. I run a 175 shot on them with no timing retard. I did melt one 104.

I believe that the autolite number for stock plugs is 105. That would make the 104 one heat range and the 103 two heat ranges. Someone please correct me if I'm wrong.

Re: Autolite Plug (3 ranges colder)

What about a 150 shot??
Presently I am running a 100 shot with 104s this year I wanted to run the 150 and I have the 103s at home but do I have to swap them in order to run the 150 safely??

I ran better NA on 103's than I did 104's anyways. I think you will be fine either way with the 103's or the 104's But I would go 103's
