This new plug has a large round knob added to it with non-slip grooves and it retains the 6-millimeter hex.
The non-slip groves in the plug allow it to be removed and installed by hand making servicing much easier. If the plug becomes difficult to remove you can still use a hex tool and there is now a place to clamp a pair of pliers to should the 6-millimeter hex round out!
Also with the addition of the long retainer on this drain plugs serves two functions:
-Prevents the plug from falling out
-Wicks the draining water and fuel down and away from spilling onto the front drive shaft on 4X4 models.
