Factory Plug Wire Resistance

[ViciousBlack97]

What should an acceptable level of resistance be for the stock wires? I pulled them off the coil and plugs and tested just the driver's side really quick, and got readings ranging from 12.5-13. These wires are factory with 101k miles on them. Am I due for a replacement soon?

I believe factory is between 10-12 k depending n wire lenght if you need some wires I have a set of ford racing for sale brand new

Just like your original front O2 sensors, I would recommend replacing your original plug wires. Hell I replace mine after 3 years, let alone 17 lol.

A good test is to move them around while the engine is running You'll know if they're bad lol
