Nology plug wires?

[cal hummer]

Has anybody installed the Nology Plug Wires yet? My friend just installed them on his Porche 911 and he said it made a world of difference.
I did a little research on them and they have a compacitor built into the wires which stores the energy from the coil and releases it all at once for a larger spark. For around $270.00 this would seam to be a cheap upgrade for the additional performance.
However sometimes things can sound to good to be true, that's why I figure someone on this forum might give me the real scoop.

thanks Cal
