Spark Plug Wires

You can replace the wires in the plug leads. Copper wire (7mm) is the best; the only reason for the use of resistive type wires is to reduce ignition noise pickup in the radio, and all the fancy electronics in the average new cage. Resistive type wires reduce the intensity of the spark, ie. restrict the current flow.

• Unscrew the compression sleeve that holds the plug wire in place in the coil.
• There is an O-ring on the wire; remove and save it.
• There is a slot in the fitting that pushes over the threaded end of the spark plug, loosen it with a screw driver and remove it from the plug end. You can push the wire out through the rubber plug cap.
• Unsolder the brass washer from the wire.
• Cut a new piece of copper core ignition wire to the same length + 1/4" as the old wire.
• Strip back the insulation and solder the brass washer onto the wire.
• Feed the wire back through the plug end and reassemble.
• Put the compression fitting on the other end and replace the O-ring.
• Smear a bit of dielectric grease inside the plug fitting; this makes it much easier to remove later.
• Don't forget to check the old plugs for carbon tracks on the insulator.
• Nothing worse for a good spark than a conductive boot. You can replace the spark plug boots with NGK P/N SD05F and XD05F.
