I have been reading a lot about the plug cables.

Many claims it increase the performance of a car engine.

But how does it increase it? Many says they have lower DC resistance,
but from my reading, the sparking of the plug occurs at high frequency,
therefore at high frequency, the current flows via surface conduction..
so the DC resistance is not applicable in this matter.

So does any of u new car owners (with new plug cable wires) have changed
to aftermarket cables? and if have...
