Nology Wires (Revisted) - Flame On!!!

This is something that I have had on the back burner for sometime. I was pulling all of my tC parts out of storage when I came across these wonders of modern automotive engineering. All arc'd to pieces I decided that it was high time to show case these lil' beauties in a fashion that only the Human Torch could do. FLAME ON!!!

Let me start off by divulging the fact that I knew that this product was all smoke and mirrors. I bought them for the blue bling factor (Yes, I have a color problem). They didn't hurt performance, but they didn't help either. That was until I had my car first dyno'd. Kenny Tran at Jotech asked me to get rid of them but I insisted on the bling. While changing my copper plugs back for the Iridium, I was horrified to discover that the Nology Plug Wires had actually corroded and arc'd across to the OEM coilpacks. One (coilpack) was almost completely destroyed with another severely eroded post. Toyota ignition coilpacks aren't cheap to replace. Needless to say, that Nology crap promptly found it's way off my motor and into a scrap box.

And the destroyed OEM coilpack.

Let the dissecting begin.


Above is the published image of the said Nology Wires. As you can see, the company claims that there is a capacitor built into the wire. From the following dissected photo, you can plainly see that there is not.

There is nothing more than a standard spiral core spark plug wire with a piece of jacketed ground strap separated by a rubber insulator.

Ok so the rubber liner can serve as a dielectric, but how is capacitance built up here?

I cannot see a series or parallel circuit here. My Radio Crap multimeter is acting up so I was unable to take a capacitance measurement.

Cause and Effect: Corrosion caused the spring loaded electrode in the boot to fail. This in turn caused serious arching at the coilpacks. This arching caused not only erosion and subsequent failure of the coilpack electrode, but harmed engine performance and MPG.

Verdict: POS, stay away from it. It may have some bling factor, but it will definitely cause damage to your coilpacks.
