Default Spark Plug wire 2 short?

Another little issue in my Monte. It seems that the 8th cylinder spark plug is so short its rubbing on the header and is melting when the header gets hot. I have come to a conclusion that its the wrong wire or incorrectly hooked up, but it seems the others are fine and its just this one that seems to be out of place.

You obviously have it either routed im properly or its to short.

The proper way is to use the stock wiring configuration.

The stock configuration is to have the wires run from over the back of the motor and then to attach from underneath the exhaust manifold.

You could get aftermarket hangers that raise the wires up and over the valve cover and out to clear the exhaust manifold and allow room/length enough to attach to the plug.

Or you could just build your own spark plug wires


By the looks of yours...
You need a set of new ones... IMO

Ok Thanks. Whats the best spark plug wires when looking at cost/performance ratio? Its a 305. Also can you verify my account? I never got a email so I am always unverified.

MSD's are good and look very nice but pricey. I use Accel because I cannot afford MSD right now.

To prevent this problem in the future replace 1 wire at a time. That way you can size up the new wire with the old wire to insure it is the proper length.


Cost/Performance of wires is relative to how much you have in your wallet. There are several brands on the market and everyone has their favorite. Taylor, MSD, Accel, Mallory, Granetelli, etc. Best bet would be to start comparing construction and ohms per foot (the least amount of ohms (resistance) the better). Then make a choice that will satisfy you.
