Scotty,

I got a 2006 Lincoln Mark LT (fancy F150 lol) with the 5.4L 3V that is notorious for spark plugs breaking when removing the original ones. Truck has 85K miles and I want to replace the spark plugs myself. What are your suggestions or tips on things to do that will help avoid breaking a spark plug? I have done this on many other vehicles but I don't have confidence in extracting a broken plug if that occurs.

I just watched this video this week. It's on a 2005 F150 so it should be the same as your 2006. Hope this helps you out. I've learned a lot watching Eric at SMA. Cross fingers you don't break any.
