The main reason for the shielded High Tension lead from the ignition coil to the distributer is to reduce any interference with the radio. Since the car is so small and everything is so close to each other (the ignition coil is close to the radio antennae and lead-in) you have to do everything you can to limit interference. Make sure your replacement wires don't generate interference. The origionals are made to suppress any interference but if you use "high performance" and they are solid core copper wires you may only hear the crackle of the ignition. The ignition wires can act like little antennaes transmitting pulses of high frequency interference. It is also suggested you run all of the ignition wires exactly as the origionals were run. Keep them separated and in the little holders as origionaly installed to prevent "crossfire". You should also at least inspect and regap the spark plugs.
