Spark plugs for your Zephyr…. The modern plugs like J6C are longer that the old style Champions This does put the terminals closer to the housing. Is there a possibility of a spark making the jump? perhaps. To be safe I do like shorter plugs. The problem with the Champion CJ 6 is that they don’t have threaded terminal studs and can’t accept the Zephyr ring terminals. I use NGK BM7A (part 6521) plugs they are short like the CJ6 but have threaded terminal studs. Just be aware that the terminal thread is metric so you will have to come up with corresponding metric nuts.
