Ignition: Spark plug wires with Pertronix

[tim333]

What type of plug wires to use with Pertronix ignitor I? I’ve heard contradictory stories about copper core wires.

Hi Tim, ordinary Radio Resistant, 7mm Silicone Core, Packard 440 Black Cables work fine with Electronic Ignition, but to be Factory made to Studebaker Lengths, they have to be Custom Made and expensive.

Wires for Other Brands of cars will sometimes be close, never perfect, but the "Make Your Own" Type where you cut to length and finish the Dist. ends will work.

Copper is never recommended for Electronic Ignition.

I agree with Rich, Pertronix recommends the use suppressor core plug leads with their ignition systems. From what I understand, the use of low resistance metallic core wire is acceptable and is what I use. I bought a roll of Pertronix 7mm low resistance plug wire from Summit Racing along with the proper terminals to make up my own plug leads as I can make them to the correct length for all of the plugs and different engines.

Suppressor core wires for EVERY type ignition..!
Copper core wires isn't even used on Race (any form of racing) engines today..! 200+ mph Pro Stock engines, 330+ mph Fuel engines run suppressor core wires.
Well, except maybe for those few that are running a Vertex (or other 60's magneto) type magneto, you can run copper wires. That's about it.

This is slightly off track, but I saw an old farm truck at a car show this summer (Ford AA) with baling wire for spark plug wires. The distributor comes up in the center of the head, and they had run short pieces of hay wire from the cap to the plugs. It was driven on a regular basis, and sounded good, running.

Cute for a car show conversation starter. Probably not good for foggy/rainy weather, but most cars aren't at shows when it is like that.

I have seen spark plug connections on model A Fords that were accomplished by flat strips of copper.

Those flat copper strips were factory stock for Ford Model A's, Model B's too.
