Although it may be due to a plug, if the plug holding force is very strong and the head is deep, it is necessary to be careful when tightening. The socket will not come off the plug and will leave it in the plug hole (it will come off the extension bar or the universal joint In the end, I bought a T type plug wrench separately, I made it here Tightening was done here It was able to do without removing the plug, but now I regret it was good if I had bought with magnets By the way the plug is BKR6EIX- It was 11P.
