Anyone try any of these so called multi spark plugs that have more than one ground electrode so as to cause multiple sparks instead of just one?
If so, what was your impression?

They don't do CRAP! Rule for electricity is that current flows to the easiest ground. So only one spark will happen at a time. Waste of money IMO.

This has mostly been my impression as well.
In fact some years ago I was at a show somewhere and they had a display showing the sparks on one of these plugs when they first came out. I think the first such plugs were called Splitfire or something like that and all they did was take the regular ground electrode and split it in two and put a little pad of platinum on each of the split legs.
I had the same thoughts and told the guy at the booth so. He said that yes, with a standard coil only one of the grounds may be used but with a big enough coil, like some of those big MSD coils back then both grounds wild be used and he went on to demonstrate it.
The reason I ask now is that its been about 15 years since I was really into that kind of stuff and then OEM systems are so much better, with much more spark voltage than back then. So, I thought I would just check if anyone had any better luck with them now.
My gut says no, or the OEMs would be using them.

I would just stick with AC Delco's. I have and I don't really go real easy on my motor with no probs. I have had MSD wires for almost a year too.
You won't need MSD coils unless your into some serious racing. MSD people say that GM coils are pretty damn good. MSD headquarters is here where I live and I know a couple of the engineers.

Yeah, my plan is definitely to start with the OEM parts.
I was just curious about it as I have noticed so many of the plug type out now.
I'm really more of a Diesel man in recent years so the whole need for these "spark" Plugs is foreign to me.
I just wanted to see if anybody has tried them, and what they thougt.
Unless like 20 people come forward ans swear by them, I don't plan to give them another thought really.

We've done some small testing in our auto lab at school and actually came out with worse results on the "Multispark" plugs. That was testing on our dyno and city mpgs

Good to know. Thanks for the feedback.
Factory AC Delco plugs are iridium tipped and the replacement interval is 100k miles or something crazy like that - they work very well. I've never had any real reason to try anything different. I used to buy into the advertising when I was younger, but never had good luck with the snake oil gimmicky stuff.
