Re: new plugs for nitrous
No way to tell by looking at them. Gotta x-reference the number on the plug against the manufacturer's specs/catalog.
Example: Autolite a stock heat range plug would be around an 25 or 26. 24 would be a little colder and somewhere around 22 is the bottom of the range. But different brands and lines of plugs the numbering schemes will be different. I think one manufacturer even does the reverse of the others with higher numbers being colder!
Almost always the last 1 or 2 digits is the heat range. For instance, Autolite 3925 is one heat range hotter than 3924, which is one heat range hotter than 3923, etc.
