Why this one
Plug sockets and flex plug sockets (M380039-C, M380041-C)
The rubber insert holds the plug as you lift it out of a deep well, and the flex sockets reach plugs set at an angle, as on twin cylinder engines.
Flex head ratchet and extension (3800F, M380023-C)
A long ratchet with a locking flex head reaches plugs under engine shrouds, and the 125 mm extension reaches plugs set in a recess.
Thread cleaners (TRC1012)
Dirt and carbon left in a plug hole can make a new plug bind or cross thread, so the two cleaners clean the threads in the head before the new plug goes in.
Feeler gauge (FG13100)
A plug gapped wrong misfires or starts hard, so the feeler gauge checks the gap on each new or cleaned plug before it goes back into the engine.
