HD SE ones are just fine. You can't beat 'em for 13 bucks.
best spark plug wires?
Who makes the best spark plug wires? any one try Sumax wires?

I use the SE 8mm but stock is fine
I just put on the KV85 wires from Magnecor. They have a very interesting write up on wires.

These are the two best articles that I have ever read on spark plug wires and why I ended up selecting the KV85s.

Who did you purchase the Magnecors from?
I'm not being a smart ass, so pardon my ignorance here, but what up upgraded wires do?
Do they improve HP/TQ?
Get better milage?
Insulate the stereo from interference?
Are they more dependable?
I know some of them look really cool, and have often thought of getting them myself, but what do they do?

I got the SE's so I would have orange wires. That's the only advantage over stock. Either your plug fires or it don't, there is no performance gain. Any good wire will work so again, stock is as good as the rest.Paniolo said:I know some of them look really cool, and have often thought of getting them myself, but what do they do?
At what mileage are most replacing the wires? I have 24,500 miles on mine and not having any obvious problems but I know some of these things can degrade over time and it is usually so gradual you don't really notice until you have a problem. Sumax looks like a good wire too. I realize stock are cheap but aftermarket are relatively cheap too.
I ordered them directly from Magnecor.BaggerDad said:Who did you purchase the Magnecors from?

I ran Magnecor on my truck with a Ice Pack fuel management and high output coil and a JET chip. They were recommended for the application.
Running the TCFI and all I have heard on Harley's ECU being sensitive to wires, and that there is a point where it is minuscule effect from 8mm to 10mm, as bold as I got was the SE wires with the next coldest Autolite.
Seems to work great.
I can say Magnecor worked with me, and Jacobs the makers of the Ice PAC, on the install, and they are just super to deal with.

"Although Magnecor Race Wires have always been primarily designed and manufactured for use on modern competition engines which require wires with high-capacity EMI suppressed conductors (which will not deteriorate with use or interfere with on-board electronic equipment, including engine management systems) and heat-resistant insulating jackets which are far super/or to all other ignition wires currently proliferating the performance aftermarket, Magnecor Race Wires can be used on exhaust emission controlled street vehicles to improve and maintain ignition performance, even if a high-output ignition system is not fitted."
As I said, I am very familiar with them, and their literature.
I am saying that the SE wires are all that I thought is needed on on my bike.
I am in no way saying they don't work, but cost difference to benefit in our application is not worth it to me.

I use magnecor wires with my 95" HTCC Heads/Pistons/SE211/44mm carb/SE ignition build.
Running Scott wires on my Fatboy and SE on my Ultra. Chose each for a specific reason and each work fine.
Most aftermarket wires reduce the resistance in the wire and offer more insulation. Reducing the resistance makes more voltage avaliable to fire the spark plug. As cylinder pressure rises so does the voltage requirement, not enough voltage, you get a miss. Higher voltage will also give you a hotter spark, that in turn will ignite imperfect a/f ratios a weaker spark wouldn't. Current will take the path of least resistance, that path could be from the wire to some place other than the plug if there is not enough insulation.Paniolo said:I'm not being a smart ass, so pardon my ignorance here, but what up upgraded wires do?

on my rat shovel 76 model i have 1 stock wire and 1 wire that came off a 62 diamond reo gas engine semi tractor. i don't know it just runs. on my 85 fl they are still the origional wires seems to run fine. if it ain't broke don't fix it.
Stock wires work just as well as those high dollar ones. Don't waste the money unless you just want the pretty colors.Mtclassic said:Who makes the best spark plug wires? any one try Sumax wires?
Maybe, but compare them on a dyno and you won't see a difference.... I checked 4 different sets and they all performed the same as the stock wires. If all the ignition system components are working properly, then more expensive wires won't make a difference.HD Tech said:Most aftermarket wires reduce the resistance in the wire and offer more insulation.

The difference in DC resistance of a 8mm and 10mm wire is .2 ohms per 1,000 ft. While that might create a voltage drop on a 110VAC circuit at with a 1,000' remote load at 35FLA, 6" at 30,000 volts ain't notyhing to worry about.
