I have a 2003 V10 and it has the full compliment of threads on it. I changed the plugs last year. As I recall the toughest plugs to get to are the passenger side front two plugs. If you do the job always get new spark plug boots. I got mine at NAPA, and I used Motorcraft plugs. On the Ford forum they advised against Autolite or NGK. I used a very small amount of anti-seize and torqued them to the spec the advised.
