New VW Beetles came with copper wire spark plug leads with resistors in the piece that connects to the spark plugs and in the Rotor... I don't know when or If, they ever changed to carbon or silicone leads..
Our last Beetle was the 1976 standard Beetle..
I have all New VW ignition parts on My Beetle's engine, apart from the Bosch 009 dizzy, which I would like to change if I ever get the chance.. I do have a High Voltage electronic ignition system to add one day.. Maybe I should look for a set of spiral spark plug leads which sound excellent, but I have never heard of anything like that, down here in Australia... I'll have to investigate further...
Thom, I wouldn't go using any?? spark plug.. looking for trouble there.. especially used plugs...
I have heard that the seatbelt interlock system broke down after a few years and that most are now "short circuited" and have been for many years.. We never had that stupid system in Australia.. Best to have the Stereo or other electronic gear connected straight to the battery with heavy leads, and a heavy duty fuse mounted near the battery.. I am a Ham Radio operator, and I have installed a heavy shielded wire to the dash for Transceivers I will be fitting.. the shield is grounded for shielding RFI..
Wayne, I think Your Beetle may have an Alternator fitted, as they are OK RFI wise, its usually Generators, Distributors and spark plug wires that cause the problems on High Frequencies.. VHF & UHF are usually noise free FM..
