How do you check the resistance of a spark plug?
Use an ohm meter to check the resistance of the wires. This can determine if the resistance of the wire is in compliance with the recommendations. Remove the wire from the engine by pulling the boot off the spark plug and unscrewing the wire at the other end. Then place one probe on each end of the wire.

What is the resistance of a spark plug wire?
In both cases, resistance of any given spark plug wire should be between 3,000-6700 ohms per foot of wire. Therefore a 2 foot long spark plug wire with 10,000 ohms of resistance would be acceptable (less than the 14,000 ohm max.), while the same wire should be discarded if resistance is 15,000 ohms.
How long should spark plug wires last?
Most of the time, your wires should last well beyond the 30,000 miles your copper spark plugs are rated for. However, there are other factors that can play a role in the timing. Damage: It’s possible for spark plug wires to be damaged.
