### ⭐⭐⭐⭐ Supercharger plugs for High thread 3V
*by U***2 on October 16, 2023*

I might have a little penance on this one as I once help on this design as a much younger person, but I can explain, these plugs here for sale are different. The plugs have changed a lot since they came out on the 2004 5.4 3v. Originally the threads would break loose from the ground shields because the crimp of the soft steel shell played double duty as the motor seat, so it was always a little thin so it could fold over in the assembly press. Then they swapped out the soft steel for 1018 high strength steel, great idea, but since the crimp and motor seat were the same, it was still not enough. Now the design has the crimp on the top, (see image of top crimp) and the motor seat is much thicker now. even though they are still two pieces, three pieces if you count the laser welded ground strap separate, they will not come apart at the motor seat. put these in without fear. But that will not help get the old ones out, I followed the official Autolite video with the carb cleaner and back and forth method and 1/2 of them stuck in there no matter. There are people who say to use the impact gun, no idea if that works, but people say it will. Either way the Lisle 65600 tool is needed to get that stinking ground shield tube out of there. What a hard job!
