Hey guys I posted this up on ls1.com and wanted to share my experiment w/ you as well. Feel free to release this info wherever so it'll help anybody out on what spark plug wires to get.

My hopes are to get this as a sticky. It took some time to get ahold of all these wires. Pics will be up soon. Please give me props for doing this...

After reading 100 threads about spark plug wires and who has the best one, I've decided to do my own test on aftermarket wires. I've got ahold of 8 aftermarket wires, all 12.5 inches long (LS1 plugs are smaller).

So why do people upgrade their wires? The theory goes that because race wires have less ohm resistance, they will reduce the amount of electricity lost in the process of being transferred through the wire. The average car transfers 30,000 volts through the spark plug wire, so every little resistance counts.

OEM plugs were created with a significant amount of ohm resistance to supress RFI interference. Aftermarket wires supress this interference while claiming to supply lower ohm resistance than stock.

There are many people who disbelieve that aftermarket spark plug wires will gain you anything. After swapping out my wires, I noticed a HP gain and smoother acceleration. My guess is that a stronger spark (not hotter) allows for a faster combustion. I cannot find anything to disproove this, so for now this theory will stay in this write-up.

So here's my test. All wires were tested at least 3 times to be sure I have accurate numbers here. Remember, they were all 12.5 inches long. I tested next to a radio but did not pick up any static from any of these wires.

stock LS1 6 in. - 351 ohms

Granatelli 8mm Steel Solid Core Cable - 0.1 ohms
MSD 8.5mm Super Conductor - 71.6 ohms
Accel 8.8 300+ Ferro-Spiral Race Wire - 166.1 ohms
Jacobs Electronics EnergyCore 8.5mm - 178.3 oms
Taylor Spiro Pro 8mm Silicone - 301 ohms
Mallory Pro Sidewinder 8mm Silicone Suppression Wire - 313 ohms
Moroso Blue Maz Spiral Core 8mm - 661 ohms
Magnecor KV85 Competiton 2.5mm - 2053 ohms

I'll write some more, but I'm tired of playing with spark plug wires. So for now here's just the facts.
