I saw the same "puck" issue with my stockers. I went with TR55s. Maybe next change Ill give the Autolites a shot.

 

i have had just about all different plugs and i would deffently go with autolite 106s

 

There are no pucks on the Iradiums.

 

just bought tr55s for 1.80 at advance auto!!

 

Another vote for the Autolite platinums. At least Ford is good for one thing!!!!!!

Did the Delco's,did the Autolights(thought I was towing a small trailer or something),did the delco's again for 1 week,went back to NKG's.My Question is,where do those little platinum pucks end up when they blow off the spark plug?(cat?).My02
