I remember someone saying that adding thicker wires would boost performance? Is this true? If so, what do I ask for when buying a set? I currently have a set of 7mm spark force plugs bought from discount auto parts as this is what the guy behind the counter said would fit my 3.5L LH car.

Do any of you run thicker wires? If so do you notice a performance increase over the OEM 7mm wires?

Thanks!

From Summit I think you can get a set of Taylor plug wires. 8mil I believeor you can go with Jacobs. I believe they are 8.5 mil. I have these on my car. I like. Jacobs are more expensive but I cannot say they are better never having dealt with Taylor. Jacobs you can get directly from them.

I wonder what would happen if you jammed like 10mm wires on there? That would prolly get the engine hella hot though. :rolleyes:

i here hotwirez are good wires but they'll eat a hole through your pocket. i think for a set its like $150 but are garenteed to boost performance. I also have the bosch +4 spark plugs which are pretty expensive but are also garenteed to boost performance.

Same here. The +4 don't do harm, its the splitfires that could chip off and some metal deposits could get in your chambers. The only time I've heard people say the +4's do something is in the 4banger cars, but above 4 cylinders they don't do anything.

I used +4's and got a boost. But I needed plugs. Hey, if you know anything about electricity, it's logical that +4's would be safer against misfires and would produce a stronger spark thus better detonation and therefore more power and cleaner exhaust. But we've covered that, just type sparkplugs in the site search and you've got it!

My best quarter mile time before wires was 16.454 at 83.94 mph. It was about 70 degrees. I put the wires in and new spark plug tubes and plenum gasket and ran a 16.186 at 84.92 mph. It was about 50 degrees this time.

i have never heard anything good about the +4's, electricity is only going to come out of one electrode no matter how many you have, 2, 4, 40, it don't matter. i've heard godo things bout split fires but anything above that are a waste of money, ust my opnion.

I have the NGK platinum plugs in my car. ALthough I have noticed no performance increase, the engine does idle a whole lot better, and I get more miles per gallon...

I personally use Autolite Platinums and the car runs great. I was just wondering if adding a thicker wire would boost engine power.

platinum sparkers are NOT recommended for the 1st gen 3.5L v6. i'm not sure about the 3.3.

as for wires, it's hard to go wrong with Taylor or Jacobs

from an earlier discussion on sparkers, quoted by 94intrepidES (corey)...also if you ask any mopar tech they'll tell you that platinum plugs are junk in most mopar engines...

--Platinums, even though most disagree on this, are not the best you can do for this engine and most chryslers. Many of you know that Neons will eat bosch platinums up in about 25,000 miles or less. These cars won't do that but aren't preferred. I can't speak on some of the brands but most are just gimics and give me a break. The splitfires are overpriced and overrated POS plugs. --

Thats what my mechanic told me. That the cheap OEM type Champions work best in these cars.
