I find nothing when I search for spark plug connectors. Is there a thread? I don't find anything on Ferrari on the Beru web site. Is this another Ferrari monopoly? Are there connectors from Porsche, et al that replace those for a 348 or Mondial? Any info would be of help.
You can buy the extensions, the wires, the connectors (and even the crimpers, I think) from Kingsborne of San Diego, Cal. They will sell individual pieces, wires by the feet, or pre-made set. The wires and connectors are cheap, the "extensions" are pretty expensive. PM Plugzit, he may even have a set for sale (I saw it for the 355).
Does anyone make extenders that clip onto the spark plug with a normal SAE style end instead of these threaded ends? As much as I'm careful when putting these on and taking them off, the little spring clips (that grab onto the threads) tend to wear out and then they start to become loose.
