Granatelli Spark plug wires.

[brigond]

Ok , I did a resistance test and here is the result of the 7mm ,12 inch coil wire that came off my car. Picture ..... youUpload.org/p0ip0pm


This is a picture of the 35 inch, 8mm Granatelli wire being tested. I just pulled one randomly out of the bag. Picture..... youUpload.org/2xqvgil

Well I can say that they do read 0 resistance like the YouTube video states. The box front says near 0 OHM.
The box also says : RFI/EMI protected, obd ll computer safe ,up to 25% more power to the spark plugs, stainless solid core, 500 degrees boots and jackets,fiberglass braid and stainless steel lock- snap connectors. Made in USA.

Take away from it what you want . I think they must be better in some way. I really don't know how much of an affect the resistance differences would make . Maybe an electrical engineer can say. Maybe these wires will end up in the " as seen on tv " section of the pharmacy.;D It all sounds logical to me.

I will update the thread after the installation. Ill let you know how the noise suppression "donut" works.

Sounds like a nice, complete package.

I'd always go for the lowest resistance wires possible. As long as there is no additional noise/interference. Looks like you may be on to something good here.

Looks like these Granatelli wires would fall under Magnacores's solid conductor class.

SOLID CORE CONDUCTOR WIRES

Solid metal (copper, tin-plated copper and/or stainless steel) conductor wires are still used in racing on carbureted engines, but can cause all sorts of running problems if used on vehicles with electronic ignition, fuel injection and engine management systems, particularly if vehicle is driven on the street — and damage to some original equipment and modern aftermarket electronic ignition and engine management systems can occur. Solid metal conductor wires cannot be suppressed to overcome EMI or RFI without the addition of current-reducing resistors at both ends of wires.

This is where the magic magnet comes in! We'll just have to see how it all works.

That was an interesting read . When they spoke about solid core wires ,they say that racers still use them . The article said that solid core wire cannot be suppressed without resistors on both ends of the wire . Granatelli says that they have a supressor ring on each wire . It's supposed to take out EMI and RFI . The article also says that non suppressed wires can interfere with newer vehicles computer and electronics . Granatelli claims that their wires have no ill effect on newer vehicles . So even if Granatelli's supressor ring does not work it should have no bad electrical interference effects with our older, non computer, carbureted chargers . The benefit of zero resistance will still be there. Only my radio will sound like an airplane taking off.

When the article talks about low resistance as a gimmick, they are refering to spiral type wires. Somehow they are saying that low resistance spiral wires are inferior. That this type of wire and materials used are sub par . That's when you realize this is an advertisement for their more tightly wound spiral type wires. Just as I'm skeptical about the magnetic ring filtering out EMI and RFI, I'm skeptical of their explanation of magnacore being better with a higher resistance. I'll let you know what I find when I install them. B.S. or not.

I guess I am just skeptical about some things.
I guess what it boils down to is that I doubt you will notice one bit of difference over any reasonably good quality wire.
I basically don't believe that the "zero ohm" wires really matter. I think it is "hype" to sell a product.
But I may just be a grouchy guy who would not accept innovation if it bit me in the Arse.
In a basically stock application.....are you going to see a difference in a 0 ohm wire and a 5 ohm (or whatever) wire? I doubt it.

Don't get me wrong....I would spend good $$ for wires on a high HP car, equipped with headers.
318 car with manifolds....I would buy a name brand replacement set under $50

Years ago....Autozone house brand wires were the absolute worst! The Red ones
I used to wonder why my old black Charger with 318 ran like crap in rainy weather.
When I became a mechanic, I found out quickly that if I saw the red wires under the hood.....they were almost always the cause of misfires.
You could mist them with a spray bottle and the cars would immediately start running bad.
I always like the Borg-Warner wires we carried. Usually fit well...and no comebacks for failures.

Realistically ,I don't believe there will be any seat of the pants or gas mileage improvement either . Unless of course the wires you are replacing we're like your red autozone wires . Truly we will never know . The only thing we have to go on is the law of electricity and its path of least resistance . My thought is that if there is the slightest inkling that the electricity will flow where it is supposed to more efficiently , the extra cost was money was well spent . Especially if the suppression ring actually works. Materials and construction probably play a bigger roll.

I didn't forget this thread . I have yet to go out there and change my spark plugs and wires . I convince myself on a weekly basis that I will go out there and start I think I need a burst of warm air as motivation . Anyway , when I do I will let you know if these wires have adequate suppression .

Todays balmy 50 degree weather motivated me to change the last 7 spark plugs and wires. Man! Big blocks are tight . I was able to do it without removing the tires. I jacked it up and did most of them from underneath. All the new plugs threaded back in very easily making my first big block plug/wire change much easier. The old plugs were very corroded on the outside but all looked to be an even beige/ light brown color inside.

I ran the car in the garage and turned on the radio. FM sounded fine , AM was noisy but I couldn't get any stations in probably from being in the garage. The real test will be out of the garage and actually driving. I'll report if the noise suppression rings work . The trickle charger kept the battery in tip top shape over the winter.

Years ago I was running Moroso Blue Max wires. They are/were silver-coated copper, solid core. Sure they had zero resistance, like you said, as you would expect from any solid core wire. Thats nothing new. BUT I would never run them on anything that had a computer. Bad idea. With the big Mallory coil I was running, I'm sure it was spraying random RF (radio frequencies) all over the place. Thats the stuff you have to watch out for on modern vehicles. And near medical equipment. And they always tell you to turn your electronic devices off while on airplances. Etc.
But on an old muscle car, the caution about the electronic ignition, Pertronix for example, is probably just covering their a**. I'm sure just a simple Mopar orange box would not be affected.
AM radio is affected, to the point mine was useless. FM will not be affected as its different technology.
Maybe the iron donut suppressor will work. But you're right, on a normal street car a person would not notice the difference from a carbon core suppressor wire.
