Does this one have a rubber grommet to protect the porcelyn FW?
Negative on the rubber grommet. I find I have a better feel without the rubber inserts. You could always stuff some rubber in it if ya need too. I use a 3" extension and my Mac floppy headed ratchet, once it's backed off a turn or so, you can usually turn them out by hand. Installation is easy too, turn in by hand till it stops, 1/8 to 1/4 turn with the ratchet, done deal. If your threads are buggered up too much to finger the plug in, clean them up with a thread chaser. Best to do it cold too, aluminum head might strip if you take them out hot. I've never had it happen, but that's what the factories all say.
