cheap autolites or NGks at the most. Dont bother with fancy plugs they wont make you faster or get better mpg.

Autolight 645 (I think that is the right #) coppers are the best for performance, Platinum for longevity.

those Bosch plugs are J U N K, all those extra ground straps are noting but detonation getters, unless your highly modded, stick wth the stock or one heat range down in Motorcraft, Champion or Autolites
