Edelbrock Heads, Autolite Plugs
 

Does anyone know which Autolite plug # fits my new Edelbrock heads and is two heat ranges colder than stock? I was told it was a 3922, but I just wanted to check with you guys and make sure.

Thanks

With my Edelbrock Performer RPM's I run autolite 3924's. That's the equivilent heat range of the Champion plugs that Edelbrock recommends. Sorry if that doesn't answer your question.

For my TFS heads: 3924's are stock and I ran 3923's recommended by MANY, MANY people. They said that 3922's are too cold if you run them on the street.
THis is for an S-trim TFS TW heads/cam/intake combo.
