Use Techron fuel system cleaner after each oil change.......it helps.
I have 26k on my 05 KR Screw;I will be removing the plugs for examination shortly. My build date is 7/05 so I'm curious to examine the plugs for any "fix" for the plug problem. Have not decided on Autolite HT0/HT1 or Motorcraft PZT1FF4.
