Spark Plug Wires

7080316 · Oct 13, 2014

From what I read I need to have solid core spark plug wires. Could someone explain to me why?

I called a local speed shop that I trust and they told me about Taylor Cable. The links are for bulk wire. Just for anyone who wants to make their own instead of buying a kit..

The auto type non wire plug wires do not stand up to the rough life of a tractor and the woods and brush and grass they have to play catch with.

" I called a local speed shop ......"

Are you looking to put plug wires on your 60+ year old tractor or your 67 Mustang?

Looks to me like the minimum length you can buy is 30 feet for $38.

Then you will need boots & ends.

Then you will need to actually cut the wires to length & install the boots & ends.

This site sells the correct wires ready to install for $20.

Your time & money, your call.

I get everything I need for making up my own wires at Napa.

They sell the wire by the foot. It's not copper core but it is some kind of stranded silver colored wire. They have all the ends and rubber boots also.

I always keep enough spare parts to make up a whole new set of wires or just one if the need arises.

Lots better than paying for a ready made set of wires. Plus you can make them the exact length needed. No problems routing and tying off like you want them.

here's the why, and the why about the why.

Modern cars use resistor / supressor wires to lower/reduce emi/rfi interference to other sensitive electronics and radio's In the old days on am radio a spark ignition would make poping sounds on the radio.. etc.

On your old tractor you don't have tons of electronics like a new car does. and here's the other part.. your ignition system , while a decent design, doesn't need a resistor in the secondary.. no reason to add a second voltage drop location. keep it all for the spark gap....

I have a set of Taylor wires on my Nissan Hardbody truck,and they claim to have less resistance than other wires. It runs really good with them on it,with copper coils around a carbon core. However,they are too limp for these tractors. Ns require too much spark to be transmitted to the plugs. lha

I did not know this and was stumped on the issue when I first heard this a few weeks ago at a training session put on by Snap-on...

Coil on plug (COP) does not use resistor plugs and if you do use them you will not like the outcome...

Any good grade of plug wire will work just find... The problem is there is allot of junk out there and that includes copper core plug wires... TSC/TISCO copper core wires are about as bad as it gets... The core will hold up but the outer shield is garbage... If the shield leaks the out come is the same no matter what the core is made of...

Why did they say that and what would be the outcome?

Misfires and coil damage...

Taylor used to make a good wire, don't know about today.
I used to run their spiral core ones on my MSD cars.
Today, for tractors, I just grab that 4cyl car kit from NAPA and shorten them up when assembling.
Belden, wire core, good 7mm shield, plug ends already installed. works fine.

just my opinion.................
agree that most of the 'tractor' wire kits have junk insulation/shield.
hard as a brick right out of the box (I always considered hard, un-flexible plug wires as junk needing to be replaced) Probably zero UV protection too.
I can't understand tractor suppliers.
Tractors need BETTER shields than a car with its countless looms,
separators.....and a hood...to protect them.
Tell the truth...most of us that have had to use a 'tractor' kit.
Day after installing them, have to grab the bundle to move it a bit when checking something....and get zapped......

I just ordered these:

as others have said you need all of the spark. These are copper and already made and reasonable.

Not even a picture of the set? How do you know they even have rubber boots at the plug end and that they are 90 degree boots?
