Spark plug wire warning!

The magnetic field created around that wire is no different than that created by a loud speaker or a motor or your ignition coil, can you feel that? This is how all of these things work, thru electro magnetic fields, this is what induces currents. The author who wrote the caution against the parallel running of those wires found out about this from Ford's shop manual as I did maybe in 1958. Doubt if you will, but you can't doubt the rules of electricity and magnatism. kotzy

With a good wire, a good plug, and good all-around electrical system, there isn't enough induction to cause an actual spark in the other cylinder.
I use "good" in relation to todays' technologies, and I doubt anyone here is still running wires made with 1958 technology.

Years ago I worked as a maintenance mechanic at an iron foundry. We had five electric induction furnaces with no less than three running at a time. There was about 8000 volts running to each furnace. When you went downstairs next to the furnaces while they were charged you could hear the humming and feel all of the hair stand out on your body. Not a good place to be if you had a pacemaker. Actually, not a good place to be without one for any amount of time. That induction felt creepy.

A buddy of mine years ago had a set of Accel 8.8 wires on his 429SCJ in a jet boat. We pulled it in the shop, closed the doors and shut the lights off. Started up the bad boy. WOW what an electrical display. LOL Needless to say he pulled off the wires and bought a different set and did away with the problem. LOL

I used to run those "super stock" Accel wires on my '70 302. They "looked" cool in the day(~1986), but they were JUNK with capital "J". If it even LOOKED like rain, it would cut out and run like crap til the clouds blew away. I used to dread getting caught in the rain(on the highway) cause likely I'd end up on the side of the road, barely running til it warmed up enough to dry off. Then back onto the road. Til I finally got rid of those worthless things did I realize how important GOOD wires were.
