Gotcha.

Do I really need an expensive 10" long swivel 16mm socket for doing the spark plugs?

Nevermind, looked at the prior owner's log and the plugs were at 176Kmi with NGK Iridium BKR6EIX and for some reason replaced again at 187Kmi with Bosch Iridium FGR7DQP+. Shop that did the fuel pump in January recommended replacement but they only have 20Kmi on them so I'm not gonna do that. Also noticed he replaced all the injectors around the same time, VDO parts.
