I would say the E3 plugs are hype and I would not use them. The plugs with multiple ground strap still have 1 spark per ignition cycle, but should last longer than a normal plug due to the erosion being spread out over 4 surfaces.
Projected tip plugs were reccomended to me by a porsche engine builder who is also a retired engine management engineer. From what I read in the bosch literature on ignition systems they have less chance of misfire compared to a normal plug. That of course is with a modern combustion chamber. All of this is probably splitting hairs that wont make much or any difference, but I find the experimenting fun.
I did also index all my spark plugs so they are facing towards the pistons and not the corner of the combustion chamber....one more thing that might give me a little edge.
I also remember reading somewhere that about the spark directon that don mentioned...
Working on spark plugs is just so easy in the packard also! They are so easy to reach compared to my other cars!
