[DeTomaso] Spark Plugs

[Jim Gray]

Thanks, Will. The numbers seem to make sense.  I just wasn't able to find a
chart with clear explanations.

The last digit is the heat range.  Lower is colder.

3926 is a normal street plug.  I was running them when I parked my car a
year ago (restoration).

By mistake, I tried 3923.  They are race plugs that foul very quickly on the
street.

3924 is one heat range hotter than 3923.  They might work on the street.
I'm guessing they're one heat range colder than 25's.

I just received my new heads and Trick Flow recommends Autolite 3924 plugs.
I can't find a chart that shows me how those compare to the older Autolite
25's I've always used in the iron heads.  Anyone know how those two compare
as far as heat range?

 

Thanks,

Jim Gray
