What spark plugs are everyone using?

[ummduh]

Change the plug wires, if they are stock 1993 then they are bad. Plug wires should not be replaced because a miss turns up, or resistance changes. The interference which they allow grows over time, no normal testing equipment can detect that. The interference interferes with other electircal circuits in the engine compartment. Replace them like plugs, every so often, like 50,000 miles.

I take it that was towards myself since you (and my header) mention 1993.

I was actually talking about my 03 Explorer. Thats what the plugs are out of.

The 93 while I had it, was a test mule.. I changed the plugs and wires in that thing so many times nothing ever had a change to wear out. And you know something? I couldn't tell a difference operationally wise between ANY plug/wire combination. Longevity aside. I never used Champion, though.

Personally though, I wouldn't touch newer plug wires untill they show age. Either the resistance will change, or the insulation will change(crack/brittle). Untill then, run them. Either way, I usually replace them from pulling the connectors out before they have a chance to go bad.

In one ear, and out the other; a resistance change doesn't happen before the wires have been bleeding interference for some time. That and the electrical charge does not flow through the core of the wire, which is the resistance you are measuring. The charge is inductive, it flows along the outer spiral windings of the wire.

Go to the Magnacor website, they have more information there than anyone else. Their wires are made to last longer than any others. Good luck,

if you want to pick and poke, wires are not capable of "bleeding interference".. The lack of adequate insulation (or degraded insulation) would cause the electromagnetic field to CREATE interference. For the most part you can eyeball the wires.(outside of resistance) But yea, common sense should prevail at some point before you leave an OE set of wires on for 14 years.

Magnecor's website is hardly the end-all be-all of plug wire theory. That game has been played before. The fact is, they're simply trying to sell their product just the same as everyone else.

If you want to be **** about it, go check out kalecoauto and pick up their spark plug wires. 100% satisfaction gauranteed.

Not picking fights.

Just about every manufacturer is propagandizing their products. My point is that about 95% of them are flat out lying, and with so much untruth being written and read, most people do not comprehend how bad that bull squeeze is.

Plug wires do not last very long, compared to what people believe. Most think that lifetime warantee means that they will never ever have to replace that part again. Plug wires are extremely fragile, many are ruined just by pulling them off of the plug.

I attempt to push the replace idea just a bit more than most because of plug wires are so difficult to diagnose. I have never experienced a clear case of a poor resistance, changed that wire, and voila, perfectly running engine. Invariably it takes a complete set of wires, and or plugs, to fix many elusive engine misses.

Countless times people, myself included, have replaced many parts, plus plugs or wires, the miss is still there, and then replacing plugs/wires again fixes the problem. The point is really that almost everyone keeps their plugs and plug wires in service for too long. They are relatively easy to replace, and relatively cheap. Throw them away whenever you think of it or experiance a miss. They should be like an air filter or fuel filter, just toss it and buy a new one. Regards,

If/when I need to replace my wire set, I'll probably end up getting another set right from Ford. They look to be very high quality, and they're not too badly priced.

You can buy some real junk from lots of the "discount" auto part stores, but getting what you pay for when it comes to plug wires isn't always true. Lots of the so-called "performance" wires are of lesser quality than a premium stock replacement set.

I really like the Belden Max wire sets from NAPA, as well as Carquest's premium wires which are made by Prestolite. They've been some of the best I've used.

For my Explorer though, just because I'm a bit of a nut as far as keeping it looking as original as possible, I'll probably get a new OEM set one of these days. They are looking a bit on the soiled side, even if they are still working fine. All this talk about wires, and my obsession with wanting to "fix" something is getting me going. It could be one of those Saturday morning boredom cures some day.

FYI, I bought Ford wires for my work truck. With a good warantee and friends at Ford, I will be able to trade them in for new wires if I want to. That isn't really possible for most other wires. Hopefully the Magnacor wires on my 98 will last longer, and they do claim a lifetime also. Regards,

I had some Magnecor KV-85 wires on my Grand Prix, and they worked great. The boot design was different than OEM, and I couldn't use the steel heat shields, but that aside, they worked excellent. Right up until I had one pop out of its clip on a trip to Arizona, and lay on the header tube. Burnt right thru.

I replaced them with some AutoZone Duralast wires since I was 3000 miles away from home when it happened, and I needed something to keep me going. They lasted less than a month. I think the extra voltage from the MSD coils trashed them. I ended up getting a refund on them when they failed, and bought some Carquest premium wires. They worked fine up till I sold the car.
I never did see if Magnecor would warranty them, and the car is long gone now.

iridium plugs are 100k plugs platnum plugs are 60k plugs i work at a dealership and thats what they change them at.
