Best Spark plug wires?

[95RedCherokee]

Well, I drive a 95 XJ sport 4wd with the 4.0 HO. Lately it started running like shit and missing sometimes. So last night I pop the hood while it was running and see it arcing on the block on one of my plug wires. Shit. So I went to autozone today and bought a set of their Bosche wires for $32. Lifetime warranty and they seem to be of high quality. I tried to search here before I bought new wires to see whateveryone though of different ones, but couldnt really find anything relevant. I'm just making this thread as a future reference for anyone looking for new wires. I'm happy with my bosche wires. The arcing has gone away and it runs good again. I changed the oil todya also and used mobil 1 synthetic and it seems to be running smoother as well. BTW: engine has over 200K on the odo. The old wires looked like the original ones. Said mopar on them :o

I wasnt looking for any performance gain out of the wires. Just wanted them to be reliable and last a long time. Anyone elses input on this subject is appreciated and will add to the help that people will need in the future.

Several of us are running Mopar Performance wires. Believe it or not, they're cheaper than the Mopar OEM.

I use Accel spiral-wound wires. They have a solid core, and use reverse-winding around the core to suppress radio interference.

Got a complete kit for $58, including 7 wires, dist. cap and rotor, and 6 Accel U-Groove plugs.

Boch is good they make Accel wire.

i just picked up a set of livewires, but i haven't put them on yet.

I've had my Splitfire 8.0mm dual core plug wires since November 1996. They've done 137k miles and still perform flawlessly. The heavy duty plug boots are great and make plug changes a snap. I highly recommend them.

I've run a few different sets of aftermarket wires and I finally settled with the Mopar Performance ones. Didn't seem as 'cheap' as everything else.

I have those on my Neon R/T, they are Magnecore brand.

Most spark plug wires, even aftermarket performance wires, use resistive core, which is latex impregnated with carbon. The latex/carbon breaks down over time and use and performance degrades, thats why you need to replace them after a while, even if they look perfectly fine.

The spiral core, solid metal wire conductor wires don't degrade over time/use and last as long as the insulation and boots, and does NOT degrade over time or use. These are gaining in popularity, with them coming as OEM stock wires.

What ever spark plug wires you buy, I'd make sure they are the SUPPRESSIVE type wire, not RESISTANCE wire. Look for things on the box or in the literature that talk about the core being wrapped in a tight spiral, uses suppression or electronic suppression technology, solid metal core that does not create EMI/RMI, etc.

Taylor makes Mopar perforamance wires. I installed Taylor 8mm wires on my 4.0 they are cut to match the factory wires and have better boots. You can order them from any of the advertisers in a 4x4 magazine.

[XgeekstarX]

got autolite professionals right now and they seem to be doing the job.

I've been running Beldin (sp?) from NAPA. They are 7mm and have a lifetime warrenty. I get new ones about every year. Just show them your receipt and get a new set.

They have never given me any problems and I think they were only around $25.

[BillyBob]

These might be the "BEST", but they are far from cheap....

yea, my bosche ones were about $32 with a lifetime warranty. So I'm happy. It runs better now. :)

Nology. Anyone know of someone actually using them? Website victory info is all from the 1990s. Surfed for 5-10 minutes; saw nothing 2005/6 current (sorry if I missed it). I can afford the ticket, but to what purpose?? Does anyone actually have a set installed??

[Sand-Dog]

$252 for a set of Nology spark plug wires? Yikes! Am I missing something, or is that just a little over-the-top for a 4.0 Jeep engine?

[Eagle]

Magnecore are the best. Mopar performance are a close second, and about half the price.

[Jim D.]

Yeah, it would seem to be over the top...'nuff said about that.

[XJFREK]

I ran Jacobs for the first 2 or 3 years I owned my XJ, then one of the electrodes stayed on the plug when I pulled it off one day. Ditched those and got Magnecor, been running those for about 5 years and no problems so far.

No one using MSD Super Conductor 8mm plug wires? Just curious, as I'm about to do a tune up on my jeep and I've had extremely good results with them on everything from 360 v8's to 3.0L HO v6's.......

[Jim D.]

Wires aside, just gotta add something. Years ago I bought one of those spark plug terminal removal tools that JCWhitney sells. Plastic handle, long metal tool with a 90 degree curve at the tool end, and then a U groove shaped tool end. Get one!!! First of all, it pulls XJ plug wires off of the plug end, like "right now" without tugging at (and damaging) the plug wires. Second - you can use it for other stuff...like pulling the plastic plugs that hold your splash shield to the frame under the engine. It's a great tool to have; cheap, too.

[Tally_XJ]

I have always used Taylor wires as they are spiral wound inner core wire. They are kinda expensive, but are very well made.

[BCKNBLK]

MSD solid core. Cant go wrong. Get the custom set and make them yourself!

This never made sense to me. Why run the same set of plug wires for years and years? Because you paid big bucks for them?

I buy semi cheap plugs and wires but change them at least once a year. To me it seems than running the same set for years and years.

Have used MSD Superconductor 8mm wires for 6 years now and previously used Jacobs.... The MSD are far superior in quality and suppression and are still going strong....

Get a tube of dielectric grease, spread it liberally around the inside of the boot before putting it on the spark plug or the terminal at the distributor cap. It helps seal out water, but more importantly it prevents the silicone boot from glueing itself to the spark plug insulator.

I've never had a boot come apart or stick since I started using dielectric grease during a tune up.

[deragheth]

TAylor wires are great. I have used them on most of my vehicles for about 7 years now. The MSD wires are great too but Taylors are usually less then half the price and are just as good. I have not had good experiences with the Accels, they tend to break too easy. As for Bosch and the other cheaper auto parts store brands, I wont even use them to replace a wire on my lawn tractor. They are just about worthless, they break easily, dry out fast and in general they hate chemicals being spilled or oversprayed on them.

Wheredo you guys get your Mopar Performance plug wires? Do you have to go to the stealership or can you get them online, etc?

... same question. What's the best place to buy them, and what's the part number? Has anyone seen them at Napa kragen or autozone?
