Subject: Re: Multi-electrode spark plugs



--------------------------


Have either trhee or four ground electrodes equally spaced around center 
electrode. The one I use most has four. This means four times as many 
sharp edges to generate a spark. With the proper system you can get 
multiple sparks at the same time which means a larger flame front, better 
combustion, and less chance of a miss-fire. It also means the gap remains 
constant for four times as long as a single electrode plug. There is no 
need to index the plugs and the turbulence at the plug is increased. All 
of this leads to better performance. But If you don't think the Jacobs 
plug wires and coils work you probably won't think these work either. Or 
is it just their other products you found fault with? I have been using 
and selling Jacobs wire and coils for more than 15 years now and have done 
side by side tests with other brands and the Jacobs is the best I've 
seen. I don't care for the way they do business and I have not found 
their computers to work well with the systems I run and sell. But their wire
and coils work so well that they're virtually all I sell. At any rate what ever 
system your run, do not run "carbon supression" wires. Use either Jacobs, 
MSD or NGK solid spiral wrap wires. Whatever you are using though you 
will benefit from the multi-electrode plugs.
