What do you suggest of the multi-electrode spark plugs?

Does spark occur within each electrode near equal intensity as the single electrode? From what I know about electricity, unless you drastically increase the subsidiary voltage, say from 20K volts to 80k volts, the expected spark from respectively of the four electrodes will be 1/4 the intensity. No free lunch you know.


Answers:    I tried a set of those by Bosch - they didnt thrill me any and didnt last any longer than a common plug. I didnt notice any raise on fuel, nor performance.
Stick next to the single electrode. Electrons will follow the path of least possible resistance, and whichever electrode may be a thousandth of an inch or so closer than the others is the one that will get the spark. You're right, no free lunch. Multi-electrode plugs are great hype but not really necessary or worth the extra money. I use single electrode plugs within everything I've ever had a never have a plug problem yet.
I come up with it,s a wonderfull way of relieving you of some of your money,gotta a short time ago love this country huh!
You will only achieve a spark from the electrode ( the multi-electrodes are only ground circuit parts) that's closer to the large voltage electrode (center). I've tried them and feel it is lately a bunch of hogwash for the normal driver.
I agree near your reasoning also. If any automaker had the slightest concept that multi-gap plugs are a trick idea they would be standard equipment within every car and truck as OEM equipment. No motors for race or street purposes show any more power with these types of spark plugs.
I know for a certainty that no Nascar Craftsman truck, Busch or Nextel motor uses multi-gap plugs. They have the greatly best MSD ignition boxes available which give long duration glorious voltage spark to the plugs - across one gap with the sole purpose.
The answer to your question is no. Since you said you know roughly speaking electricity, you should know that in a circuit, it other look for the shortest path to ground. Even though you own a multi-electrode plug, which electrode has the lowest resistance will spark, not all of them. The prime reason for those multi-electrode is that so you enjoy more than one path for the spark to occur. Meaning that if you have 4 electrode, let say 1,2,3,4, and # 3 electrode have alot of resistance than 1,2 or 4, which ever one has the tiniest resistance, that is where on earth the spark is going to jump.
Even if though it's singular going to produce one spark, let's assume for a minute it produces two. Your fuel is not going to burn any more quickly as far as I can conjure up. If you're standing in a puddle of gasoline and whether you neutral one lighter or you light two -- it's simply not going to concern.
