Has anyone seen or tried these? I got a set for my 94 ranger and they seem to have produced good results. Smoother running, quicker start and I havent checked mileage yet but from what I see on the odometer and fuel guage they seem to have made a difference. So just wondering if anyone can shed any light on their use?

Snake oil.
Marketing hype.
There is nothing about them that makes them worth double the cost of OE spec Motorcraft spark plugs.
The spark will travel through the path of least resistance and arc from 1 point to 1 other point. So it is a fallacy to believe that having multiple tips or a solid bar on a spark plug will do anything to change how electricity works.

Any improvement in drivability will be from swapping old part for new parts and will be noticed every time you change old spark plugs and put in new spark plugs.

 

Absolutely agree with this ^^^!

Having been a member here since 2010 or so I've read many, many times of over-hyped spark plugs and COP's that produce nothing in improved performance or MPG's. We do read time after time how brands other than Motorcraft or Autolite are responsible for noticeable problems with drivability either immediately or soon after installation.

Added to that is the cost of genuine Motorcraft plugs and coils pretty much rivals the aftermarket crap if you shop around just a little bit. Since the supposed economic reason to go off-brand is now gone use what Ford designed and had built for their motors---just makes more and more sense every day.
