Hemi spark plug wires

[dart6]

Hi
I'm having no luck finding the resistance of these 8mm silicone wires online. I relaced the plugs with BPR5ES but there seems to be a slight misfire at low revs. The misfire was more pronounced with the original RN14YC plugs.
Anyway i'd like to test the wire resistance but i don't have a figure to go on.
Are these silicone wires any good they appear newish?

I would try to isolate 1 cylinder at a time by grounding the wire to see if you can find the cylinder misfiring. Then measure the resistance and examine the wire carefully for damage or possibly a bad terminal connection. If the wire looks good then measure the end-to-end resistance of another wire that is closest in length to the suspected bad one. If they seem to compare closely then I would start looking at other potential causes of the miss.

Another thought. Idle the car at night in darkness at night and look for any sign of arcing and leakage from any of the wires.

A little spritz of water from a spray bottle will start the fireworks at night.

If the wires ohm out less that 25k they are fine. check the insulators carefully for tiny burn throughs, same thing with the boots themselves.

How do you ground the wire?
I did the visual last night before i posted, nothing to see

I'll do that tonight

I would try RN12YC plugs over the 14's. 10's if you can find them. I doubt it is the wires causing the misfire on a Hemi since the wires go no where need the exhaust manifols/headers.
