Default Spark Plug Wire comparison (Read this before purchasing WIRES!)


Spark plug wire comparison between Accel wires, MSD wires, Magnecor wires, Mopar wires, and Granatelli wires.

We're frequently asked, whats the difference between all the wires that are available for my car ? We know it can be confusing, because, other than color of wire, and price, its hard to know which wire is the best quality wire for your money.

Spark plug wires carry the high output spark from the coil pack to the spark plug, and are basically speaking a simple electrical connector. So, the higher quality connector, wiring, and shielding will provide more of your spark from the coilpack, to your spark plug.

One easy way to test a spark plugs conductivity is to test the wire with a OHM meter. Testing a spark plug wire's ohm resistance will display how much resistance there is to the current that passes through the wire.

The lower the number, the lower the resistance, which means that more current will reach the spark plug. The lower the resistance, the better quality conductor materials are used in making the spark plug wires.

Now, onto testing the wires. We will display the wires from top to bottom from lowest resistance to highest resistance. <b> Remember, the lower the number, the better the wire set is. You should be buying the lowest resistance wire set possible.



(Granatelli wires, pictured above, 2 OHMS)

Here we have the Granatelli wires. These wires were the lowest wire OHM resistance wire we have ever tested, at 2 ohms of resistance. Granatelli uses a stainless steel core, wrapped in silver plated copper wiring. This is the highest quality wire we have ever carried, and the wire that we strongly recommend.



(MSD wires, pictured above, 33 OHMS)

In second place, we have the MSD wire set. Compared to the Granatelli wires in first place, these wires are red in color, and come in at 33 ohms of resistance to the Granatelli wires's 2 OHMs of resistance. The MSD wires are still good quality though. Msd states on their boxes that they use a copper alloy conductor for their wires.



(Accel wires, pictured above, 124 OHMS)

In third place, we have Accel wires. These use a copper/alloy wire core, and are has a 8mm silicone jacket. These wires had a cheaper feel, and look compared to the other wires, but still had a great, low resistance.


Mopar wires 390 OHMs

(Mopar wires, pictured above, 390 OHMS)

Fourth place belongs to the Mopar Performance spark plug wires. We measured these wires to have 390 OHMS of resistance which is quite high, but still acceptable.




(Magnecor wires, pictured above, 1548 OHMS)

Fifth place place belongs to the Magnecor wires. Magnecor wires had the highest resistance out of all of the wires we tested, coming in at 1548 OHMS of resistance. (In Magnecor's defense, they claim that low OHM resistance wires are not a measure of quality, you can read more about it on their website here: Magnecor Race Wires )

Good info. I also want to add that as a wire is just an electrical connection, the quality of the whole wire including its insulation and end connectors should be considered. I ran a 50 trim with no heat shield for about 6 months and the wires one by one were failing due to ambient heat. I'd rather have a fresh set of oem's or magnecors than some questionable msd's. What is your favorite wire change interval?

Why don't make this comparison with heated wires??
And see the real resistance of the wires on normal operation of the car!!!
Just my 2 cents.

PD: Add the stock ones to see the benefit too!

Very good idea, i'm with him.

The 250 degree heat of the engine bay isnt going to change the resistance of the electrical conductor.

Ive spent a LOT of time setting this comparison up, and its proven to show the resistance of the wires just fine. If youd like to do a test comparison of the wires installed on a car, share the results with us. I guarantee that you wont be 3% more or less variance with the results I found though.

That comparison would take no longer than 10 minutes. All you did was hook up a ohm meter to 5 wires. Is there some other testing done that you didn't say?

Your right, hooking up the ohm meter to the wires was easy.

Setting up the wires, with the ohm leads so that the leads wouldnt move, or come unconnected before taking the photo took some time though. (standard style test leads with straight connectors)

Taking all the photos, resizing them took some time.

Uploading the photos.

Writing all the text for comparison.

Ive never said this is a textbook comparison, with hundreds of photos, and dissections of the wires, etc. But, it is a good comparison, even if its a simple comparison.

Interesting comparison.

How about real world power numbers? Any dyno testing?

I just wanted to bring the comparison for normal operation on a car an see benefits. That was my idea. But when you test a part you take it to its limits harder than manufacturer specs an see how good is it. Not to said that your comparison is bad. But then why buy 10mm (expensive) wires when 7mm or 8mm (not too expensive) work much better. Insulation is done for a purpose and when a normal wire is heated resistance change. Just giving you an Idea

Go here( Electrical resistance - Wikipedia, the free encyclopedia ) and read where it says temperature-Dependence

im pretty sure they would do better than any of those wires

Interesting comparison guys! Good to see that you guys went above and beyond what other vendors have done on this subject. Also in true SRTForums form, people complain that you didn't do a good enough job.
For those of you who are concerned about thermal damage, look here for a simple solution: DEI Aluminized Spark Plug Wire Sheaths: DEI-010409 - summitracing.com
