spark plugs

[Rich J]

I've had one spark plug fail on my Duratec 2.0. Now I don't trust the other 3. Can anyone reccomend a brand, and heat range?
Thanks

What is the nature of the failure? And the brand. I've been having trouble w/ a cylinder as well so I'm wondering...

There was no resitance when the center electrode, and the top of the plug were connected through a multimeter. I've had another "100,000 mile" plug fail in my pickup, and have heard of several others with the same problem.
