how long have you guys gotten out of these wires? km/miles/length of time

 

how old are they? how many miles on them? they're cheap enough where you should probably just buy another set.

 

They're a little over a year old. I don't know about you, but I can't throw 50-100 bucks at my car on a whim. I want to make sure parts are defective before they get replaced.

 

Pretty sure it goes by the foot.

thanks

 

Replace Them.

 

thank you for your incredibly relevant reply. i've heard of guys getting years out of them and wanted to know about...get this..you're not gonna believe it.....TESTING THEM TO SEE IF THEY'RE STILL GOOD. not like i put that in the original post or anything...that would just be silly.

 

measure their length and then measure the resistance and divide each to get an idea of how many ohms/foot they come in at. Any that are significatnly higher in ohms/foot than the others indicates a problem.

 

X2 - is there a symptom/problem you're trying to solve? Mine (red) are 7 years old/27k miles and the car runs just like it ever did...which is just fine.

 

No issues to speak of...my cap/rotor/plugs need replacing and it seemed a fool idea to replace them if I had bad wire to send the spark. this is in a 1990 ltd - no headers yet

 

To me what seems even more suspect is wondering if a 1 year old set of wires have lost their ability to conduct electricity effectively. Change the plugs/cap/rotor. If all is well after that, don't worry about it.

 

I really don't understand this. It's wrong for me to wonder if parts might lose efficiency after a year, and want to test them?


You can make a guy feel welcome to ask questions here, that's for sure.

 

Mine (red) are about 10 years old. I wonder how the resistance is, but have not tested.

I want a new set of black wires anyway, so currently searching. But nothing has ever made me feel the wires were "crap"

 

Feel free to test them,but you need some baseline to compare them to.
Maybe find a new set,at a parts store,and take your Ohm meter and get a reading on a couple. Then compare to your old wires.

 

Resistance for the Ford 9mm are 1000 ohm/ft, per the Summit Catalog.

 

i know its an older thread, but i measured my fr wires last nite, new, 1000 ohms per foot.(maybe a fuss over on some)....The awesome advance/autozone high suppression wires were 7 and 8k ohms per foot...pure sh&t in any book. The old wires from my wifes v6 explorer were 11k:eeek:......This makes me wonder......with coil packs/module wear out wires quicker?

 

11 K ohms isn't anything compared to the infinite resistance of your spark plug gap under compression pressure.

But yeah, I run the red Ford wires, too. Probably 9 or 10 years now without any problems. Get a cap and rotor with brass contacts that won't burn or corrode.

 

already did!

 

Ohms is a measure of resistance...

So basically when you measure ohms in a spark plug wire, you obviously want the ohms reading as low as possible.

For instance, in my current job we have ground clamps and plugs that have 100ft spools of 12ga. wire inside a coating. When we install new grounding wires or change out a plug or clamp, we have to measure the ohms resistance from the new clamp or plug, all the way to the end of the wire.

Now a perfect reading is 0 ohms, which means there is no resistance in current. But the acceptable range of resistance is 10 ohms maximum. But usually as long as the cable is in tact we usually get readings of 0-1 ohms for a total length of 100ft.

So measure your plug wires and se what you got...Take notice of the different lengths as well. Measure them from the actual terminal lengths, not from the boot ends. For an indiviual wire, measure the ohms, take the total length of the wire and divide the 2. When you have that number, that will tell you how many phms of resistance you have per inch of wire. So let say for example you have 12 inches of wire, with a total resistance of 5 ohms. that is .41 ohms of resistance per inch...no let say you measure another wire that is 18 inches long with a total resistance of 10 ohms. That is 1.8 ohms of resistance per inch...Now the rest of you wires all average between .40 and .50, so you know you got a bad plug wire and you know which one it is.

 

IIRC correctly they are somewhere on the order of 1,000 ohms/foot. As long as they haven't rubbed or burned through they should be fine. I've been running them for about three years.

 

They are only 1 year old dude, get over it and just change the rest of the stuff.

 

I have had great use out of my Ford racing Blue wires. Put them on the car 12 years ago maybe 15k miles. They have been on and off dozens of times. Still like new. Just ohmed them. Still in spec. I recommend them for the price
