Mattias78 Posted June 26, 2015 Report Posted June 26, 2015 Hi! I need to buy carbon (suppression) core wires! But i don't know how to explaine to the parts store what they are! (In swedish) So if somebody could explaine whats the diffrens are between solid wires and the carbon wires! Thanks! Mattias Quote
casper50 Posted June 26, 2015 Report Posted June 26, 2015 Found on the web. As mentioned earlier, there are three spark plug wires types: distributed resistance, inductance (MAG), and fixed resistor. Many American vehicles use distributed resistance spark plug wires. They’re made with fine strands of fiberglass impregnated with carbon. The carbon core creates very high resistance. Carmakers rely on that high resistance to reduce radio frequency interference (RFI) “noise” generated by normal ignition system operation. RFI not only ruins radio reception, but in severe cases it can interfere with the sensors and computers used to control the engine. That’s why it’s so important to buy the best spark plug wires you can afford. If your vehicle came equipped with distributed resistance wires, replace them with the same type. Japanese manufacturers like Honda, Acura, Toyota, and Lexus prefer inductance (MAG) style spark plug wires. MAG wires are made from a spiral wound core of copper/nickel alloy wire. The spiral winding creates a magnetic field that reduces RFI. MAG wires also have less electrical resistance, so they need less current to fire the spark plug. If your automotive ignition system was designed for MAG wires, you must use buy a set of premium spark plug wires of the same type when it’s time to replace them. Don’t install low resistance MAG wires on a vehicle designed for high resistance wires. Finally, some European cars use fixed resistor spark plug wires. These wires are made with steel or copper wire and include a resistor inside the spark plug boot. Once again, if you vehicle came with this style spark plug wire, replace them with premium spark plug wires of the same type. Quote
46Ply Posted June 26, 2015 Report Posted June 26, 2015 A translation would be.... kol ( dämpning ) kärnorna = carbon (suppression) core wires. Quote
Jeff Balazs Posted June 26, 2015 Report Posted June 26, 2015 Mattias; Do your spark plug cables have a solid metallic wire core? or are they suppression (resistor) type cables? If they have a metallic wire core then that may be causing a problem with the Ignitor. Jeff Quote
Mattias78 Posted June 27, 2015 Author Report Posted June 27, 2015 Jeff! Thats what i'm trying to find out! Can't tell the diffrens between them! Is there any way to id them? Quote
greg g Posted June 27, 2015 Report Posted June 27, 2015 Look under the cap at the distributer end of the wire. You should be able to see the core material where the contact is crimped to wire. Why are you needing high resistance wire? Are you running some sort of high performance ignition, special equipment or upgraded radio receiver? Quote
Mattias78 Posted June 27, 2015 Author Report Posted June 27, 2015 Greg; I was trying to instal a pertronix ingnition but it did not work! So i got the advise to change to suppresion wire, because solid wires could mess with the ignition! The wires that i got on now is a SAE class F, MF Have not a clue what it means! Tryed to Google it! But i don't understand the half of what is says! Quote
Andydodge Posted June 27, 2015 Report Posted June 27, 2015 Mattias.......my understanding is that electronic ignitions like the Petronics and HEI's must use silicon or suppression type plug leads, when I installed the Langdon HEI dissy I also used these type of leads or wires and never had a problem........have attached a pic of mine........as you can see I used red leads, being a hotrodder the red colour made the car go faster but black leads are available.........lol........andyd Quote
Solution Barabbas Posted June 28, 2015 Solution Report Posted June 28, 2015 Measure the resistance of one of the spark plug wires. If the resistance is over 3000 ohms/foot (10,000 Ohms per meter) you have the carbon supression type wire..If the resistance is about 500 Ohms/foot you have MAG or Spiral type wires and if the resistance is low you have old school solid core wires.

Mattias78 Posted June 28, 2015 Author Report Posted June 28, 2015 I really suck at electronics!! So here is a pic of the wire! Can anybody tell what type it is? Looks solid to me! Quote
Andydodge Posted June 28, 2015 Report Posted June 28, 2015 Mattias..........that looks like a silicon or suppression wire to me........that's what I'd use in an electronic dissy..........what you DON'T want are wires that have a solid piece of copper wire inside them..........what you pictured looks fine to me.......andyd Quote
Mattias78 Posted June 28, 2015 Author Report Posted June 28, 2015 Andyd; That sound great!! 1 less expense! Thanks!! Quote
