System working harder ? You mean faster don't you ? That's why with high rpm's, you buy the beefy high output coils.
The split fires, do give more power. This I know from my own testing. Yes, it is a marketing scheme. So is everything else. Except, a lot of them don't work. My self, I like the 5-6 neg electrode style. There are a few things you can do to plugs to help out. Not just the name.
What's wrong with my sense of Humor? I thought I was doing quit well.

And, don't forget, you can always run the Super Sonic Plugs !!
Denny,if you don't have a chassis dyno or an engine dyno how do you know the Split fires are making more power?
You are not going to tell me you can feel it in the seat of your pants now are you?
