Suit ALL GQ and GU Models
This particular one is used for the gearbox.
They have a Magnet fitted to the end, so any small metal shavings hopefully get caught and don't keep circulating through the gearbox.
We also have a different style to suit the diffs, available separately in our online store.
Note: This Should not be fitted as a fill plug, as it is quite a bit longer than a standard Plug.
