Didn't think so.
And that was my point.
There is no need for a fine wire ground strap.
Fine-wire plugs fire at a lower voltage threshold. This is a net reduction in power and slows the erosion of the ground electrode to a minimal level compared to a single plat plug that is firing the "wrong" direction.
Ford's own testing indicated that the fine-wire design with a single platinum fine wire center electrode last as long as a -PP plug with the added benefits of a less-stressed ignition system on waste spark systems.
