TR6 TR6 Ignition Wires

I have continued to use the OEM green high tension ignition wires we commonly call spark plug wires. The wires to this day still do very well; no arcs/sparks, broken insulation or other apparent aging.

My question is about the relationship of electronic ignition and the non resistive wires and plugs.I'm thinking the OEM wires may be conducting much more current and putting more load (heat) in the electronic switching module. I have never changed the resistive "run" wire so I know I am not getting the full advantage of the electronic system but I am a little reluctant to make that change with out knowing the effect of resistive vs nonresistant plug wires?
 
That's a good question. I have the Magnecor solid copper on mine and I don't know what they are classified as.
 
You can check them with an ohm meter. Equal lengths should have similar resistance. I found my aftermarket wires to have much less resistance than the 'green' wires.
 
David, I am not happy with my Magnecore wires. One came out of the boot the first try and another moved a fair amount. Is there a stated resistance # for respectable length?
 
Vettedog,
I am not an electrical expert,but like to try and understand these things.
I would think that the elecronic ignition switches the primary ,low tension ,windings of the coil,and the load and heat would be dependent on its resistance and how long switch is closed.
The spark plug wires are the gound of the secondary winding,so
I dont think they would add more heat to the pimary winding gound switch,(points or electronic)-Or I am totally wrong
Looking forward to hearing an expert answer to your intresting question
Hoping to learn,
Tom
 
You have to careful with the Magnecor's out of the box. The plug boots are too long as furnished, IMO. Even with silicone grease I pulled a wire out of the boot right off. Not pulling the wire - just a slip off the boot. Magnecor fixed it no charge other than shipping. I then cut about 1/2" off each boot (maybe 3/4" - don't recall) and have had no problems since.
 
You mean I can have them replaced. I fixed it with a kit and know it is not close to good enough.,
 
I bought mine about three years ago and had none of these problems. I guess I was lucky back then.
 
On the plus side - Magnecore sez the wires will last the life of the car. If handled correctly.
 
I looked through Magnecor's home page and then to the products. It appears Magnecor no longer makes the solid copper wires. All I could see were 3 categories: 1.)"CN"; 2.)High Performance; and 3.)Special Purpose. Within the three categories there appears to be two different wires in each category for a total of 6 different wires. Maybe I am miss reading the tech info but for conductors Magnecor appears to use 2.5mm and some wires are 2.0mm spooled Stainless Steel.
 
David, the only specification I could see in the Magnecor site stated 2.2K Ohms/ft. That is 2200 ohms per foot. I hope my solid core OEM green colored wires would be about 1.0 ohm/ft. Did you get the solid core copper wires or the stainless steel spool over the "Ferrimagnetic (what ever that is) core"?

Don, I'm using Street Fire by MSD spark plug wires. It states 500 ohm's per foot on the box. I found them to be very close to that. It is an 8mm universal set (Part #5551) that comes with a tool to crimp the terminals in a vice. The set was for a V-8, so there's plenty to work with. Got them at O'Reilly's.
 
This is for the Wedge , but I am horrible at crimping wires
 
It's probably more the tool you are using than your skills Don. Especially for these bigger connectors.
 
You mean Paul, I might not be as anempt as I think?
