Looks like we can add a new plug to the list of options. Haven't seen any reviews, but E3 has released the E3.70 for the 3 valves. Looks like they run around $10 a pop online.
Can't tell if they are one or two piece.

The TSB has been revised several times since it was first released. I believe that the earlier revisions did say to do it with the engine warm.

It works very well. Going by memory, it's a bit confusing at first but once you study it and read the docs if you have them it works great. When it breaks off, you put the steel dark colored one in first, you thread it in and then you use the push tool to 'push' in the broken plug. Careful, do not push it all the way down but enough to screw in the main thread tool. You then take it out and put the aluminum sleeve in and put in the main reverse thread 'main tool' and turn it in. You then use the big nut and it will come right out. If you have the instructions read them and take your time and study them. The tool saved me, 5 out of 8 broke. I hated the job but 'face your fear', say a prayer and use the tool correctly. Good luck and be positive. Forgive the not so good description but its late but I feel your pain. Btw, I had the exact socket size of each nut and bolt, made life easier.

I have a F150 screw4.6 with a build date 5-07. You said in the forum that I did not have that plug problem, but here you say before 11/30/07 so my truck would fall under this correct, if i'm understanding this right. Does my trucks 4.6 have 2 valves or 3valves. Thanks GATORB8

They came out with the 3 valve for the Mustangs before releasing it in the truck.
