Yeah trust me Ford doesn't want you anywhere near those sparkplugs. Those f*ckers can be a nightmare. They either break off in the head and it's a b*tch to get em out or the f*ckers come shooting out of the head and it's a b*tch to keep em in. I always tell folks not to f*ck with em.Yep. 240k miles and quiet as a mouse queef believe it or not. Spark plugs have been changed twice with no problems. *Knock on wood*
