    Spark Plug Replacement on 2011 5.4 Triton V8

    I have a 2011 Expedition with a 5.4 Triton V8 that has about 156,000 miles on it, and I know it's past due to replace the spark plugs. The problem is I've heard all these horror stories about the spark plugs breaking when you go to remove them. I took it to Firestone, and they won't touch it...
