Plug wire lie?

I was looking at plug wires on e-bay and came across some Granatelli plug wires that claimed a 15% increase in gas milage. Have any of you tried these wires? They claim 0 resistance per foot of wire. It won't take much on my 6.0 Silverado. I figure this is just advertising hype but am a little curious about their claim. They are pretty expensive

Save your money for a Good AC Delco tune up when needed.

think about any claims these scamers make ....If you could simply reduce the plug wire resistance and gain 15% on MPG why didn't GM do it ..??????

there are no aftermarket products that can cause MPG gains , just a scam....

Thanks guys, That is about what I figured.

O resistance per foot yeah right. It don't matter what the material is theres gonna be resistance. I put a set of MSD plug wires on my 6.0 and didn't see any difference, but they cost right about the same as what ac delco wires cost. you might be able to gain some out of the e3 plugs but still no guarantee.
