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.

Its not wire. Its conductive carbon fibers.

It's still wire. It's long and it conducts electricity, that's close
enoough for government work. Who cares if it's not technically made out of
metals.
