Yes. My ticking engine needs breakable spark plugs so it can tick some more Sent from my iPad using Tapatalk - now Free
Replacing the spark plugs on the 5.4 3V is no big deal if you the Lisle tool. I broke every single spark plug and one was stripped. Original plugs replaced at 148,000km. Took me 3 hours, taking my time and I saved $1,000. Good choice to go with factory plugs. I've only heard of a few occasions where someone had issues with factory Ford plugs, but I've heard of numerous occasions with people had problems with Brisk and Champions.
