I'm hoping a wire pro here can tell what kind of wires these are by looking at them. They seem thicker than stock -I did a quick and dirty job of measuring and came up with 34mm circumference, which would make these 10.5mm wires. These wires have a loose jacket around them, which is particularly evident on wire #2 in the picture.

I'm hoping to find what brand these are so I can research if I should even bother putting them on, or if I should just keep the Belkins I put on last year (before I knew I could get decent wires for LESS cost than the $108 Belkin set from Napa).

One other question:
I recall having two shorter wires with the Belkin set too (and they can be seen as the two leftmost wires in this set), but only one of the two would properly replace the coil to opti wire. Where's the other one go? I think I threw it out on the Belkin set.

 

I am going back with the stock wires on mine.

 

I don't know what brand of wires those are but the second short wire you mentioned is most likely for a different application...maybe one without the opti like the HEI system...but included in the set to make it more universal.

 

I guess it doesn't matter too much anymore. I hook each up to an ohm meter, and their resistance is all over the board.

0-15 inches long acceptable ohms are 3,000 to 10,000
Plug Wire #1, ~14 inches long = 20,800 ohms
Coil Wire, ~10 inches long = 600 ohms
HEI Wire, ~10 inches long = 67,000 ohms

15-25 inches long acceptable ohms are 4,000 to 15,000
Plug Wire #2, ~18 inches long = 31,800 ohms
Plug Wire #3, ~15 inches long = 15,600 ohms
Plug Wire #4, ~20 inches long = 9,000 ohms
Plug Wire #5, ~19 inches long = 700 ohms
Plug Wire #6, ~24 inches long = 4,000 ohms

25-35 inches long acceptable ohms are 6,000 to 20,000
Plug Wire #7, ~34 inches long = OVER 1,500,000 ohms
Plug Wire #8, ~29 inches long = 26,000

As you can see, ONE plug wire is within the acceptable range (#4).
I guess I'll be trying to get my money back. :/
