[Diy_efi] OT - platinum plugs burning up wires

[hal sumption]

Adding resistance to the circuit will lower the current and reduce the likelihood of burning the wires.  From what I understand, the purpose of adding resistance to the plug wires is to reduce radio interference they may generate.

  Some plugs have internal resistance, others don't.  I was under the
  impression this is more to avoid burning up the coil, not the wires.

  Rick, that does sound like bunk. Your leads may have been on the way
  out.
  The way I see it, doesn't make much difference what the electrodes are
  made of, only a small amount of current flows when the plug fires. The
  gap has more influence on the current, and never enough to burn out a
  lead.
  My question is, did the dealer keep the plugs?

  Sorry for being off topic, but I know there is a lot
  of knowledge in this area on this list, and this might
  be of interest to discuss (remember the recent plug
  discussion?)
  Recently I had an issue w/ a Hyundai where the plugs
  were replaced w/ platinum at a tune up. A few k-miles
  down the road, the car began running poorly, and was
  taken to the dealer where it was diagnosed as having
  'burned up ignition wires'. The service advisor stated
  that you MUST NOT use platinum plugs in these cars
  since it will cause this to happen.

  My question is: What is different about them that
  would cause this, it sounds like 'bunk' to me, but am
  looking to the vast world of knowledge on this list to
  get some insight.

  Thanks
