I'm looking for some expert advice on ignition wires. I have gone through 2 sets of Ford Motorsport 9mm wires in just 6500 miles. By "going through them", I mean that one of them starts to break down and I get an ignition miss. The wire resistance still reads ok, but there is definitely something breaking down in the wire because a simple wire replacement cures the problem. 3200 street miles to a set of ignition wires seems unreasonably low.

Anyone else ever have this problem? Are Motorcraft wires that bad? Or do you think something is causing premature failure?

Standard plugs (they look fine, with no wear).
