    I prefer Hf performance stranded copper wire operating in conjunction with either / or suppressed spark plug connector suppressor plugs

    Re: Spark plug wires

    John, are you having any problems fitting the caps onto the wires, as in do they fit snugly?

    No problem fitting the wires. I’m using the original side entry cap.

    Re: Spark plug wires

    Ok, thanks. I need new wires, and I’m unsure which way to go. I read some older threads which were talking about the bumblebees being too thin to get a good tight crimp on them. Thanks for the info,

    Re: Spark plug wires

    I've never had much luck crimping stranded copper wires, bumblebee or black (bumblebees look cool, but I've never understood how one set of stranded copper wires could be 'high performance' and another not; I think they're more of a marketing gimmick). If you have an original type distributor cap the pointed terminals screw into the wire, and at the plug end the resistance plug caps others have mentioned do the same (there's a prong that looks like a sheet metal screw inside). I recommend you put some silicone/dielectric grease in both the distributor cap holes and the plug cap holes to help prevent corrosion. AFAIK, the wires are all 7mm, which was a de facto standard for cars of all makes up until, oh, the seventies or so when there began to be issues with the radios more people were putting in their cars and we went to 'suppression' wires. I use resistance plug caps and resistor plugs, totaling about 30Kohms.

    Re: Spark plug wires

    Im with Bob here , wire is wire is wire the only difference is the insulation and if you have a basic point/condenser system then so called “high performance “ wires dont do nothing IMHO.
    The better insulation was introduced to prevent radio interference and that annoying buzz over the radio .
    I dont listen to the radio in my Healey its the original BMC single bezel speaker so its useless anyway .
    if the car runs well save your money , its like snake oil “its going to produce more HP if you use it “ Yeah right !!!!
    "If it aint broke ....dont fix it "
    " Thats not an oil leak ..........its a special automatic British rustproofing system "

    Re: Spark plug wires

    HI ALL:Just a thought

    I've never understood how one set of stranded copper wires could be 'high performance' and another not;

    Well in the above case :

    The gauge and number of those strand wires will dictate its flexibility and usefu llife

    Similarly:
    The insulated coverings rarely supply any real electromagnetic radiation suppression
    ;this is usually provided by under lying supprt designs.

    The French required shielded igntion systems o the imported Healey cars to address this.
    noisy power converters used combined with inadequate filtering caused much of the problems in early designs
