I'm guessing he's just talking about the wire extensions that go into the valve cover to reach the plug. As far as I know, the new Civics still use a standard electronic distributor/single coil ignition. I avoid new cars like the plague though.

Well, I'd do as mentioned before in this thread: have the wires measured for resistance. That's pretty much the only way to tell if they look OK externally.

I'd be very suprised if wires that new failed. Is the car no longer under warranty?

Also, I've never heard of plug wires being sold individually. If money is an issue, you can get a basic, generic brand set of four wires from Autozone for fairly cheap.
