I'm no engineer, but common sense tells me that for spark to occur, there must be a charge and a ground. How are four prongs going to work any better than one in providing a ground? It is the simplest path for spark to occur between the electrode and the prong right beneath it. What convoluted path would the charge have to take to make spark with four prongs. Sounds like a recipe for misfires to me. But I could be completely wrong - I'm open to correction.

I like running the MSD 8.5 wires (40 ohms per foot), and NGK TR55's gapped at .055. The wider the gap the hotter the spark. Run as wide a gap as possible without getting misfires. I'm happy at .055 because the gap will widen over time & I don't want to change plugs as often.

.045 is better for cars running N2o.

as far as the plugs go the whole purpose for the 4 prong is so that when one prong gets burnt up or carbon build up the spark has 3 other possible paths to ground, it just helps the plug last longer, the spark doesn't split 4 ways it just takes the path of less resistance to ground. and for the comment before about the platinum plugs, they aren't to bad on a n/a engine but don't use them on turbo or supercharged engines, probably not a good idea on high compression either because the platinum heats up and stays hot, it takes a while to cool down so if you have a beefed up engine you could be at risk of detonation because of the plug being so hot it could ignite the a/f mixture in the cylinder before it is supposed to. at least that is what i have read in many magazines and heard from fellow mechanics.

Thats what I was thinking.

Still simple path, not convoluted. Electricity always wants to flow to ground and will take the shortest path of least resistence.

Thats probably the best that you can get.

The stock wires are pretty damn good for a mild engine. I'm still running stockers on my H/C/N package, though that may change shortly. I use TR6s gapped at .038 for the nitrous..
