[Roadsters] spark plugs - resistor vs non-resistor

[ljordan704 at netscape.net]

 Hmmm, this is interesting. Isn't most wire, except racing wire, resistor? So if you use a resistor plug, what would happen? I think most people use the resistor plugs automatically, thinking to eliminate interference with radios etc. Why are the two together bad?

The overall point of the original posting is quite accurate - the
resistance reduces the generation of EMI (electromagnetic interference).
More of a problem in the days of AM radios :-)

BUT...
Check your plug wires first.

The rule is you should use resistor wires, OR resistor plugs,
but not both. So if you have installed resistor wires at some point,
then resistor plugs are redundant and contraindicated.
