Tech Question

Don L, Alton IL, 1996 Dodge Dakota 360

Hello, love the Mag , anyway I am looking for some decentplug wires for my 360, But why use wires with resistance? Would zeroresistance be better? I remeber a few yrs ago in my Dippy and my Aspen , Iused metalic core wires from Blue Streak Standard and I had no radiointerference, and the MP ignition with chrome box and Accel coil workedfine, and it seems they had almost 0 resistance.

Please explain


“Almost” is the key! There are three types of plug wires: The factory’scarbon-soaked-linen resistance core (the black conductor type), the solidcore (usually copper) type, and the newer spiral-wound, metallic-resistancecore.

The carbon ones aren’t great in high-heat applications – the core getsbrittle, and then, if flexed – snap! But the solid cores can generatetremendous amounts of RFI, which can not only make AM radio receptionannoying, it can be bad enough to interfere with modern engine controlelectronics. So they should be though of as “full race”, and offer virtuallyno advange on the street.

The third type – spiral core, have “almost” no resistance, but stilleffectively supress RFI. That’s the hot ticket for hi-po street use, and, nodoubt, what you had on the Aspen and Dippy. And what you should have on yourDak!
