Count me solidly in the camp that believes there is virtually zero horsepower gain from one brand of wire to another... not squat...

I would be be looking at heat shielding/ability to last being around heat, fit, and even appearance if its important to what a hobbyist has going on under the hood....

Hot rod magazine in fact a few years ago dyno'ed about 10 different wires and said the same thing in an article expressedly to clarify this myth......

So... not being a politician, I will buy wires that fit and are a nice color that matches my underhood....
I find it kinda funny that a fuel team would prefer one wire over another( assuming quality brands being used) because they make way more power than can be used anyhow... thats why clutches are set up to slip so much.... all a wire has to do is conduct output from coil to plug...it isn't rocket science..... good quality wire, connectors, insulation....you are plenty good to go....anything else is politics
