M12x1.25 spark plug repair kit p/n 6604212H tooling includes
5 inserts and sealer. This extended tooling is only needed for
a special Ford 3 valve spark plug M12x1.25x21mm taper seat
insert. Ford heads are around 6" inches deep to the spark plug
which requires longer tooling.
The wrench which is the second black tool 4-5/8" inches long,
rotates all the tools. The wrench has a 1/2" inch hex at the top
which can allow you to extend the tooling with a socket further
if needed.
