I purchased these plugs at a Napa auto parts store several years ago. Shortly after my dealership contacted me for the 100,000 mile service, plugs and wires would be included so here they are. These fit a 2004-2008 f-150 2WD 4.2L V6. AND many other applications.THE BOX SHOWS STORAGE WEAR BUT THE PLUG ARE NEW<SIX ARE INCLUDED (6)
