Try checking plug gaps, I ran mine at .050, a little less than specified for the standard Duratec, so they spark earlier. Seems good over 6 months.
Closing the gap also diminishes spark intensity. My experience has been that you should set at the high end of spec for most cars. You don't close the gap unless you have boost.
