Well, that's sure unfortunate. I care for my father in law's focus, and the iridium plugs really were good for 100k miles. In 35 years of caring for cars I have never been so frightened by the sounds and feel of unscrewing a spark plug though.

This is the one with a "permanent air filter" so they were thinking about eliminating maintenance. Boy this is going to suck when it is clogged.
