Most domestic vehicles use spark plug wires with a fiber glass core covered in latex graphite, which provides between 10,000 and 12,000 ohms of resistance per foot of wire. But this varies with wire type Do you really want to put all of that resistance in the signal path??? https://youtu.be/FpPBxN_FzmA |
I am not aware of any fixed resistor in ages, and copper, not in forever except for racing, and even then you want to control the spark to prevent fuel cavitation. Most domestic wire is not simply a fiber glass core covered in carbon filled latex. Most are variable spaced fairly high resistance stainless wire. They variable spacing is so they can have consistent performance independent of wire length, hence why today you buy vehicle specific wire sets (or should). Don't pick some random site on the web for your information. Most mechanics won't have a clue about the inner working of spark plug wires. |
