stupid question # 428

if silicones insulate electrical wires then what are silicone
spark plugs leads (wires)?

The silicone is the insulator in them; the conductor is, usually,
carbon-impregnated fiber of some kind (basically a big long
resistor).

Why don't spark plug leads get made out of metal, copper or
whatever?

They make lots of RFI.

And they don't when they're made out of resistor wire? Huh. Weird.

No, not as much. The resistance built into the length of the lead
chokes of the high frequencies that cause most of the interference !
