If you want the best performance, go with Granatelli Wires.
They have 0 OHMS of resistance, which means they give you the best spark. The stock wires have about 600-700 OHMS of resistance.
Granatelli dyno tested a 2006 Corvette Z06 with the stock wires and then their wires - and picked up 10WHP from a stronger spark. I believe they have the video on their website.
I got them for $100 from Summit Racing on sale, they are normally about $180-$200.

Stock wires are fine.
To expect any significant power gain from good condition stock wires is just silly.

For Coil near plug applications you wont see too much more of a spark difference between aftermarket and original plug wires. Im not sure what the resistance rating of the stock wires are but it cant be too much.

Hey guys its Mike from Granatelli Motor Sports here to elaborate on how our coil near plug wires work. I understand that there will be some confusion of how our wires work. A relatively new product is naturally going to have some misconceptions. Our performance ignition products are an industry first, and as stated by a previous post, have "0" OHM resistance.
Stock plug wires on GM vehicles have around 600-900 OHM resistance. Our recent test showed about 800 OHM resistance as accurate for new stock GM wires and confirmed 0 OHM resistance with our wires (see GMS wires test on a new C6 Z06 video). After installing our GMS coil-near plug wires, we made 10 RWHP and 17 lb-ft torque on a Corvette Z06 nearly straight out of the dealership. Depending on the condition of your ignition system is how much OHM resistance the wires have. I recently pulled wires off of a '01 Camaro SS and noticed a heavy amount of corrosion throughout the wires. For a car that is 5 years in age with a significant amount of corrosion on the stock wires should raise concern to anybody that has performance in interest.
That being said about stock wires, lets look at our lead competitor's wires. One company claims their wires have 40-50 Ohms of resistance per foot. They also claim that they have the "lowest resistance of any helically wound wire". Did they forget about us? Helically simply means "pertaining to or having the form of a spiral", so that includes our wound stainless steel core. Lets say we took 8 feet of our spark plug wire against 8 feet of their spark plug wire, which is close to the length of a set of Camaro wires. Their wires would read 320-400 Ohms of resistance and ours would read 0.4-0.8 Ohms resistance. Big difference.
Now lets take a look at quality and design. Their wires contain a "ferro-magnetic impregnated center core"...in laymen terms, a circular polarized core. One long dissection and I still don't know what it's made out of. Then, on the outer shell, they also used Kevlar for strength. Kevlar is not a defined material and is simply considered as heat-resistant fibers. Then they used copper for their conductor. Ours is a solid, stainless steel core. In all obviousness stainless steel is less likely to corrode and is a much better conductor.
Back-to-back comparisons shows we are not playing the "smoke and mirrors" game unlike the rest. Our product is the best quality and conductor hands down.

What we have done was to design a wire that has the absolute least amount of resistance. Although we still can measure a small amount of resistance (0.05 Ohms), the amount compared to stock (600-900) and even competitor's wires (40-60) is significantly less.

Granted they are stock and the more air/fuel you feed your engine the more of a spark you will need, but what is the limit for the factory plug wires and coils?

We all know the stock intake can probably withstand over 500 HP, but who wouldn't have removed the restrictive intake by even 350 HP? The main benefits from swapping out the stock wires is the HP gain you will get, the temperature tolerance our wires can handle (such as if you were burning up stock wires due to headers), and the stainless steel braids which won't rust like stock and the competitors wires.
