I have Tempest Plugs in my Lycoming O-145-b2 (REM37BY, 5/8” plugs, 18mm threads).

But I'm having an awful time finding the right socket for these plugs!

Aircraft Spruce has the right size, but has this note:
Quote:
T-557 3/8” drive without magnet PN 12-00710
T-558 1/2” drive without magnet PN 12-00712

Not for use on Tempest spark plugs.

There's not much room so I need a fairly thin-walled socket.

Anyone else solve this problem or at least point me to the right socket?

Thanks!!
