Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
with normal leads ive never noticed any difference as the core is most likely the same just the shielding increases diameter, only time i could hear a change in the engine note was when i fitted the zero ohm leads
Cheers matethink they only use 8mm they are the https://www.granatellimotorsports.com/catalog/Coil_Near_Plug-24-1.html only got them to run with ethanol as much more fuel volume to ignite, im now going back to standard style as ive moved the coil packs so have to make my own leads
only thing i noticed besides a change in engine note was my windscreen mounted gopro gets a small static interference i believe from the leads, there gains im not sure of as i never done back to back tests and dynos can vary to easily, and there price now is crazy back when i got mine they were same cost as stock replacements i wouldnt get them at what they are now best spent on other areasThe thicker leads simply have thicker insulation and the same core conductor material when I looked some years ago.
Since the leads can’t short to earth when operating, the thinner leads must by design have enough insulation to prevent such arcing. Thicker insulation simply won’t reduce arcing since it’s not a problem to begin with.
So I ’d save the few dollars and put it towards something else unless it’s the aesthetics of coloured leads you’re after
(edits follow) Also want to add that the ignition system is designed for a specific resistance in the leads and within the plug itself. If they are changed to zero ohm leads, there must be some impacts to the spark timing and RFI (not in a positive way). In any case, zero ohms conductors are usually described as (near absolute zero degree) superconductors which would make such a zero ohm room temperature conductor worthy of a Nobel prize. So i think it’s a marketing term more than something real. I also doubt they have RFI test report to back up the other marketing guff. Basically if gains were so easy, vehicle manufacturers would have been using such leads years ago.
