Silly question, but I’ll ask it anyway.


Just wondering, but can you make an interconnect with spark plug wire?

why is or isn’t this done?

It will work just fine! But the neurotically obsessed wire maniacs will be in a state of perpetual doubt about its "sound"!
roberjerman is right. Of course, he thinks clothes hangers are fine, too.
Darn it, all this time I was using clothes hangers to suspend my cables off the carpet.  Thank you @geoffkait 😊
Silly, no.
Clever, outside the box thinking, yes!

One can’t help wondering if the car would run better if the spark plug wires were all in the correct direction. Hmmmmm...

Why yes, MacGyver, yes you can. But it would be a lot more impressive to make one with pencil and paper. Graphite is conductive, you know. 

Oh wait! I know! What about Wrigley's chewing gum wrappers? Hey, this is fun!

why is or isn’t this done?

Uh, sound quality?
Or. Your could have said the reality of the situation- you just don’t know. Got it
If he just went ahead and said that, then he wouldn’t be his usual charming self...
@last_lemming

Wouldn’t work for interconnects. There is only one conductor covered by a very high voltage rated insulation. You need two conductors for an interconnect. A supply and a return.

Next problem the conductor is usually made of compressed carbon powder. Carbon is not a good low resistance conductor for low signal voltages.

But a carbon core wrapped in helically wound OFC copper wire (2 per interconnect) that they sell for making spark plug wires might sound pretty sweet. You’d need one heck of a wide plug, though...unless you direct soldered it.

Yes but the real MacGyver would know this and use two spark plug wires. Connected to a distributor so you could switch components really fast. Not only that but supply and return? The real MacGyver would know that’s plumbing not electrical. You’re not even on the right aisle.

Then there’s this,

“The Nanofiber main strength is its exceptional midrange purity (we feel the midrange is absolutely as open as with the Indra - the flagship of STEALTH analog interconnects). The Nanofiber offers first class overall presentation: excellent speed, very good midbass and deep bass performance, sweet treble - but this sweet treble is not extended enough to qualify for the reference level - i.e. truly complete with the Indra when it comes to critical listening. However, there is one area where the Nanofiber actually outperforms the Indra: these pure carbon cables offer the least "listening fatigue" of all cables we have ever tested (our own and other brands). In our opinion, the Nanofiber is the best choice for pure listening pleasure - all by itself, or in combination with the Indra or the Metacarbon. If you like the Quad ESL loudspeakers, then you are most likely to prefer the Nanofiber to any other cable.”
You mean someone stole my idea already!!??
The nerve...
They stole it 20 years ago. You should sue.
May I use your time machine?
You must be joking  thats junk.
Nah ebm.
GK time machine is the real deal!
I spend most of my time in the future. I only come back here for the jokes. Besides, they don’t have audio forums in the future. The trolls got too out of control. 
You could do it. It would probably sound awful with most spark plug wires.  Most spark plug wires are highly inductive (and resistive) stainless steel wire around a core that may or may not be conductive carbon. I guess if you like your music really warm, you may like them :-)
Most domestic vehicles use spark plug wires with a fiber glass core covered in latex graphite, which provides between 10,000 and 12,000 ohms of resistance per foot of wire.  But this varies with wire type   

Do you really want to put all of that resistance in the signal path???

Not very well if the wire is of type 1) distributed (carbon core) or 2) fixed resistor.  They have more resistance than copper to reduce RFI interference.  It does not matter at 100,000 volts in the car but it does in an amplifier.
I am not aware of any fixed resistor in ages, and copper, not in forever except for racing, and even then you want to control the spark to prevent fuel cavitation.
Most domestic wire is not simply a fiber glass core covered in carbon filled latex. Most are variable spaced fairly high resistance stainless wire. They variable spacing is so they can have consistent performance independent of wire length, hence why today you buy vehicle specific wire sets (or should).
Don't pick some random site on the web for your information. Most mechanics won't have a clue about the inner working of spark plug wires.


Say who has better sparkling high fidelity speaker wires? Nascar or NHRA? AutoZone or Riley Autoparts? Will carbon resist electron puddling? So many things to consider here!

I do have to ask this question though....

Why/how on earth did you even come up with the question to begin with?
I work on old Porsche’s. I was installing new wires on my 944 Turbo last weekend. The next day I made some interconnects with Duelund wire. The soldering iron was next to where I placed the old spark plug wires. Imagination took over from there. Voila, question;)
@geoffkait - clothes hangers are perfect for their intended use!  LOL


@last_lemming that’s  So awesome 😎 
....I can see it now, coming to a screen near You...

I do believe asvjerry, in his "unique" style of writing, is lampooning this thread by melding and likening them to an announcer’s overzealous advertising spots for drag racing, stock cars, and monster trucks.
Either that, or he forgot his meds again...
Maybe you can use a distributor cap as a distribution network  !!!
Amazon interconnects are cheep but OK quality. I would not waste your time or possibly cause damage to your gear. As long as you have two conductors per interconnect you are good. Next would be the shielding. Is it good enough? I am more worried about your system.

@geoffkait ,
Actually, you spend most of your time in *our* future, which would be your present.
Tell me, does everyone have terrific hair in the future??
@last_lemming ..." I made some interconnects with Duelund wire."
So how did they work out for you?
@thecarpathian.....Precisely.....;)

Plug wires, coat hangers.....exhorting a whole new level of audio esoteria, hmmm?  And you're saying I'm sans meds?

(Actually, the only ones of late are the Rx'd variety from the cardio kidz.  I keep harassing them to 'legal' medmary,  It'll let me keep it out of the lungs of those who would just....abuse it.....:(
I do it happily as a public service....)

"...I'm open to fall from grace...", however...;)
But the local PD has no humor, and the 'likely suspects' suspect I'm an unusual narcotics officer....

...and your excuse is?

Regards....J
Me?
I fall down a lot...
*L*  Understood....I bruise if you look at me Hard...

Oh, and Thanks for the 'unique' comment. *S*
Like Leonard Cohens' Bird on the Wire (note my little pic), paraphrased:
"I've tried in my way to be free..."

....but I've merely become expensive.

Sometimes you just can't win....;)

Good morning....at least, here....EST....

@rixtherick - they sound nice and open. They seem a bit more mellow than what they replaced, but they are brand new. They replaced Kimber PBJ’s which seemed to have a bit more upper mid range bite.

And you are a mechanic? I am. The reason for the carbon wire is radio interference, primarily emergency. You can still tell when someone is running multi strand wire, pull up beside them you'll hear it through your AM or FM radio stations. Most hot rodders that have MS wire DON'T have or use a stereo while running.  The old MS wire was OK speaker wire at best. A LOT of insulation for HIGH voltage 15-25 for the old point/condenser style, and 50+ for HEI, can really bite you.

Better off insulating a piece of solder, hee hee.  I mean where do you people come up with these ideas? LOL 

It's the thought that count's RIGHT..

spark to prevent fuel cavitation.

Cavitation in a hydraulic term referring to a pressure drop on the suction side of a hydraulic pump, where pockets of current atmosphere, form bubbles. Those bubbles actually collapse and carve out the cavity pre chamber to a pump. Same with hydraulic Motors, You can hear cavitation..tearing up a pump.. restricted lines, pump and motor killers.

The spark is controlled to prevent air/fuel PRE DETONATION. ..A fuel KNOCK or RATTLE is caused normally by a carbon build up that gets so hot it PRE DET. due to excessive advanced timing (BTDC) a Fuel rattle. Shutting off an continuing to run (DIESELING), again glowing carbon, particles with a fuel and air supply, BUT NO controlled spark, Firing under pressure, dieseling.

The definition of a diesel is simple 2300 psi, it will not be a diesel without it.  NOTHING ELSE.. 2300 psi.. You can obtain 2300 psi a few different ways... Different story..... See learn something every day...

I know I use to teach engines gas/diesel 101 201, 301. Yup yup
That was a while back...NOT MOTORS ok....ENGINES..

Work best with Audioengine speakers while listening to a certain Traffic album.
Love the time machine humor.
Spark plug wires are not suited for audio.  They come mostly with resistive material  that inhibits  RF so it does not cause popping sounds in the car radio.
oldhvymec,
When I need some help with RF design or mitigating RF noise, I don't consult my mechanic. Ditto when I need help with fluid dynamics.

"Still using multi-strand wire" ? .... I think your knowledge is either limited or out of date w.r.t. spark plug wires. Modern high performance spark plug wires are a single strand of typically thin stainless wire coiled (variable spacing) around a core of fibreglass or similar, but sometimes around a secondary conductive core of carbon. The stainless wire being thin is resistive, just like a carbon conductor, but you also have a helpful and controllable inductive component, plus as you can space the coils, you can better control conductivity over length.  From the NGK website for example, "NGK ignition wire sets are engineered to meet strict OEM tolerances using variable pitch wire winding, creating resistance to radio frequency interference."  You can also consult the image on this page:  https://www.holley.com/blog/post/plug_wires_build_them_right/, or this one: https://www.musclecardiy.com/wp-content/uploads/2016/05/107.jpg.  With modern cars having high output per displacement, and fuel efficiency/emissions requirements, advanced construction like this is now common.

cavitation: Rapid forming and collapsing of vapour pockets, sort of like on the wall of a moving diesel cylinder, but hey.

The definition of diesel is rapidly heated air reaching a suitable temperature to ignite fuel, but hey, why get hung up on semantics. That of course differs from dieseling where you do have heating due to compression, but can have a lower ignition temperature due to the hot spot in the combustion chamber.  2300psi is a relatively meaningless number that represents a very specific set of conditions w.r.t. initial air temperature and fuel type. It is not, in any way, form, or function a definition of "diesel"   (nor have anything to do with this conversation).
This is true about dieseling and in fact if you put a drop of oil on the back of a high performance air gun pellet, the heat generated by the rapidly compressed air in the chamber will ignite the spot of oil and increase the pressure of the shot..., maybe to the point of splitting the barrel.

MSD 8.5mm Super Conductor Spark Plug Wire Sets 31649 is a great set of wires and a great bang for the buck!
Ok. So what I’m getting is, it’s a NO on using spark plug wires as interconnect cables. But hey, it was an interesting thought experiment;)
No such thing as a silly question, as theirs always silly people to answer.
Reverse thought experiment: would the car run better if you used audiophile interconnects in place of the stock spark plug wires? 
. 2300psi is a relatively meaningless number that represents a very specific set of conditions w.r.t. initial air temperature and fuel type. It is not, in any way, form, or function a definition of "diesel"   (nor have anything to do with this conversation.

The conversation no, the meaning yes. An engine that fires under compression combustion, (diesel) requires 2300 psi to achieve that.
Whether by charging the combustion chamber with ADDED air and then by piston compression or by simply, sucking it in, close the valves and compressing the chamber. Fuel is added via injector at a given time, and a given fuel pressure, either BTDC, TDC, or ATDC. This is an analog system, PT as in cummins. (yes oversimplified answer, but I'm a simple Retired Master HD Mechanic) YES it is old school..
The spark plug thing was at best oversimplified. I do appreciate you updating me on the wire thing... Interesting. I'm was a Detroit, Cummins, Deutz and Cat engine certified. Yup Yup.  Been a while though, I'm retired now. thanks for your input though. 

So the new spark plug wires sound like a 20,000.00 speaker cable in the making. After all the stuff I read about, networks, tungsten, white gold, nickel silver, why not add SS and carbon to the mix? 

Respectfully and with regards
