Has anyone used any of the newfangled spark plugs in place of regular plugs. I was considering the E3 or Splitfire to get better spark. Are these really any better or is it all just marketing hype. I've got a 5.0 HO block, GT40x heads, Performer RPM intake and Holley 600 4 barrel.
Been running autolite 45s with no problem, a little colder than the 26 but I think 'll swich to th 26 this year
I think I will switch over to #26s myself, in my '73 8.5to1 smog monster. I'm glad I read this thread. Thanks guys.:Handshake
