Title: Which spark plug should I use?
Post by: james on January 26, 2021, 05:17:01 PM

Have a 427 FE with autolite plugs ap3924. Which one should I get? Autolite platnum.  Autolite copper core.  Autolite copper core resistor or autolite double platnum? Or is there another brand you would suggest? Thank You!

I run plain copper core in my older race engines.  The dragster heads use a NGK plug that has some other weird-tanium material but is the correct thread and heat range.  The 351Cs and such have all run Autolite copper core plugs for years.
