Got bored and done a plug wire comparison

Well I figured I would share this info with you guys I checked the ohms per foot on 3 popular sets of plug wires and a 12" length of wiring and a couple of spark plugs (i was bored) and figure someone can apply this somehow in there car.


12" test length ohm meter set to 200k

Mallory sidewinder 8mm 5.5 ohm

taylor spiro core wires 8mm 0.04 ohm

Accell Super Stock 8mm 4.9 ohm

14 gauge automotive wire 0.0 ohm

Autolite platinum spark plug 14.0 ohm

autolite copper spark plug 146.0 ohm

Good info. Got a regular NGK you could test? How about some MSD wire?

I couldnt find any laying around i figure maybe this can be added to as time goes.And become something usefull for the future.


Anyone have msd wires,autozone wires,etc they want to cut in a 12" section and test?

The plugs were checked from tip to tip and not the ground strap.

am ohm is a measure of resistance to electrical flow, so a lower number would be better

Plug wires have resistance by design. This reduces EMI (electromagnetic interference). In the early days of TV when people had antennas on the roof (anybody here old enough to remember the days before cable?) when an old car with copper plug wires drove by your TV would go crazy.
It also gives a lot of static on AM radio.

In modern cars with sensors feeding back to a computer it can cause all sorts of problems.
