Best Plug Wires for my application

[gsx951]

I may be wrong but VDC is going into the coils and to my knowledge there is not a rectifier in the circuit to convert that to VAC. So the plugs are fired with VDC.

Even if they are fired with VAC, a megaohm meter is still the best way to check resistance of wires. We use them at work to check three phase AC motors and the wires that power them all the time. As it is the best way for us to check if wires or a motor is bad or not. Using a regular ohm meter does not give us accurate results when troubleshooting these problems.

Aren't rectifiers used to convert AC and not the other way around?

granted megaohm may read "more precisely"...but if all you are doing is checking resistance then ANY meter (that reads 0 when touched together ) will do.

I have also tested NGK vs stock and there is a lot more resistance in the stock.

Plug wires are resistive to suppress the emission of noise. Magnecor is a really good pick for audio freaks because of superior suppression.

I read a test once where a fellow did the OHM meter test amnd the Magnacores came in last, like 2000 ohms/foot compared to some less than 100ohms. Great electronics discussion here but off track on what wires guys have had good response with. I will repeat that I tried the Magnacores based upon reputation and NGK blues were just suggested one time so when it came time to buy wires I went with the NGK's and found them to be better in my lowly opinion based on a simple amount/distance the respective wires would have their spark jump when pulled from a running motor. I chose the NGK's and they work great and I will buy them again. Included in the tip on them was that they lasted much longer than the mag's. Thanks guys, mark

IMO this is a simple resistance test & a meg meter isn't needed for accurate enough results. Most digital multimeters are accurate to .1 of an ohm and I'm sure thats accurate enough to find out one wire reds 150 ohms & another reads 1500 ohms . But back on topic, the Accel's have been good to me

Not off track at all.... noise suppression is the ONLY difference. There is no difference in performance from any plug wire as long as the wire is functioning and not defective.
Go to Magnecor's site and read the tech pages, Steve tells you the same thing.
Plug wires are voodoo for newbies to obsess over, buy what makes you happy and move on to something that does impact performance.
In my experience, carbon wires like the NGK or O.E.M. are good for a couple of years max. The carbon burns up after a while and they do degrade. this is backed up by my engineer pals at GM who actually suggest hurling carbon wires annually. Magnecor on the other hand, is a stainless steel wire and does not degrade as long as the jacket is in good shape. Most Magnecor failures are self-inflicted and not related to the quality of the product.

Factory wires use carbon conductors to reduce spark current as a method to provide suppression and are not affected as quickly as race wires (conducting full coil current) by water and oil in spark plug wells — although the engine will lose power!

They seem to think plug wires will provide better power.

I thought that I had read somewhere that its possible to do both. But everything I can find says you are right, that they only convert AC to DC.

This is the point that I think needs to be made; which wires are good in the long run. I can buy a ssautochrome header that may work as good as a greddy at first but what happens 1 year from now (no, no don't get into that arguement. I am just giving an example). While comparative resistances are important to get a cleaner spark to your plugs so that you WILL have better power vs a "dirty" spark, that comparison is useless if the wire breaks down quickly. Our engines do run hot therefore the wires get a good taste of temperature range. While I run the OBX @ 10mm because I am not a big "afficiando" of plug wires (I have other power adders to worry about), I would think that the degrading of the wires is just as, if not more, important than slight variances in resistance.

OH yeah the tip I got on the NGK's said tbhey lasted longer than the Magnacores also. I must admit though that I change wires like oil, every year or 6000 miles, whichever comes first. The differences between the 5 most popular DSM wires are probably so close as to be negligable. Mark

i started a thread a while back ago that has all the info you could possible want about spark plug wires to these threads wouldnt be needed .. sooo.. enjoy!
