Question:

What range in ohms are spark plug wires normal?

What are the range specs when testing resistance on your spark plug wires ?

Answer:

Solid wires (high performance) are under an ohm (tare of the wire). According to the first link, from Popular Mechanics, spark plug wires are supposed to have 10,000 to 15,000 ohms per foot. According to the second link, from David Kucharczyk, silicon wires have 10^9 to 10^11 ohms per meter. As the wire wears out, the resistance might get higher but not lower. Resistance dampens electromagnetic noise that would make your radio noisy and might interfere with sensitive electronics in your car (including the ECU (Electronic Control Unit)). High performance wires are sometimes made with solid wires to provide hotter spark, but they will electromagnetic noise. Some people prefer solid wires because they are more durable since solid wire doesn't usually wear out, but the insulation on the wires might wear out (causing arcing). Nology wires have metal braid shielding (something like a coaxial cable), and are designed to shield the electromagnetic noise. The outer shield is grounded on only one end of the wire. If both ends were grounded, a ground loop might form, and that would cause unwanted current flow within the grounded shield, producing unwanted electromagnetic noise. The shielding produces about 35pF of capacitance (the outer shield is one plate of a capacitor, and the wire conductor is the other).

For the best answers, search on this site https://shorturl.im/OZ4TL 2 -1 ohms doesn't make sense. Take a better look at your meter, no offense intended. Generally they have positions for different levels of resistance, from 2 ohms to 200k ohms; choosing the right setting will give you a better idea of the right reading, which should be around 2000 ohms. You needn't change them for the heck of it, but it's not a bad idea. The corrosion/rust is normal, it wouldn't cause you any trouble.
6-12 ohms? Huh That person is WAY off. Stock type plug wires will have 3,000 to 5,000 ohms per 1 foot of wire Cheap parts store plug wires may have 4000-8000 ohms per 1 foot of wire High performance wires like MSD will have 40-50 ohms per 1 foot of wire
