What are the best low-resistance suppression type plug wires you've used?

I have the Moroso Blue Max wires on my car currently and was surprised to find a resistance value of close to 1000 ohms/foot. I bought them because I heard they were good wires (and they seem to be other than higher than expected resistance) and because they're a nice shade of blue. No yellow or red wires for me!

I would prefer a cut-to-fit wire set available in black or blue.

Opinions and experience? How low of a resistance in ohms/foot can you get in a spiral core or other suppression type wire?

Will,
Probably any new resistance wires would work fine, but like all of us, you just don't won't to give up any performance loss to something as simple as plug wires.

According to my experience and that of many others, there is no readily discernible 1/4 mile performance difference between most good wire sets. I believe Jim Hand still uses J.C. Whitney wires on his wagon. Many of the Nascar teams use the Moroso wires due to their performance and also excellent suppression characteristics. We have used the Taylor 8mm spiral core wires for the past six years on a street/strip car for about 40,000 miles with no performance issues and no radio interference.

For many users with an increasing amount of digital electronics in their cars, including EFI, the importance of EMI suppression is very important. From what I understand, the measure of resistance with a low voltage ohm meter is not an accurate way to measure the high voltage pulse current flow capablity of a spark plug wire. I beleive the Magnecor web site has some interesting information along these lines.

So, if had a set of Moroso Blue Max wires in good condition, I wouldn't worry about resistance readings of 1000 ohms/foot. We've been happy with the Taylor wires in blue except for some discoloration from header heat or oil.

The best ones I have seen for a reasonable price are the MSD Super Conductors. They are around 40-50 ohms/foot and aren't that expensive. You can get them at Summit for 69.95. (MSD-31369) Probably the lowest resistance wire you can find for that price. They say that even with that low resistance they still supress noise like a 1500ohm/foot wire would.

The MSD Super conductors are red with grey boots and they do make a cut to fit set although I'm not readily sure of the part number.

Will, look into the Taylor "409" or Thundervolt. Both available in blue or black at around $100/set. These particular wires are 10.4mm but they also have other 8mm. They fit well and look great!

Crane fire wire claims 25 ohms per foot.

What Rhett said. I've used the Moroso Blue Max wires for at least 10 years now. I don't use anything else.

MSD,
Same, same as moroso but less money.. [img]tongue.gif[/img]

JUST CHANGED FROM MOROSO TO MSD SUPER CONDUTORS NO DIFFERENCE IN PERFORMACE NONE

Probably no difference on the track but I agree with Rockey about the Taylor wires. We have used them over the years with no problems and I like the fact that they come in black.

larry davis · 08-17-2002, 03:13 PM

I concure w/ the Taylor contingent. But, would agree that the Moroso & MSDs are top shelf.

I got a set of the Spiro-pros I've had well over 10 years w/o any issues.

Delco gray HEI wires seem to do fine. Lots of sets for free in the U-Pull-It yard....just but an HEI for $5

Floyd Hand · 08-17-2002, 07:22 PM

Autozone next to the best ones for me. Can't afford their lifetime set.

I should've mentioned in my initial post that I realize changing wires will almost assuredly not gain me anything performance-wise. After all, the coil will provide whatever current is necessary to jump the gap (provided it's powerful enough and there aren't any easier paths to ground than through the plug gap). What I'm really trying to do is lower the load on the coil, though what Rhett says about resistance not being a good measure of the wire's ability to carry a high current pulse could make the whole issue moot.

Thanks for the info guys. Guess I'll just clean up my Blue Max's and use them again later.

I did see some Mallory "Pro Wires" that were black on a car at a show on Sunday. Anyone tried them?

Lee · 08-21-2002, 06:45 AM

Will, If all 8 wires check-out within 10% or so, I wouldn't worry. Most of the Moroso's I've checked over the years have been closer to 800/ft, but I wouldn't worry about 1000. I've tried 15+ sets of different wires on different cars over the last several years, and the Morosos are my favorites.

Oh, you can now get the Moroso wires in black in other colors as well.
