Still trying to decide whether changing the spark plugs on my wife's Outback is a win or if I should have just paid a shop to do it. Cylinder 4 took various combinations of 3" extension, a swivel joint, and two different 14mm sockets depending on how far in the plug was threaded. And that was just the nonsense I had to deal with after managing to get to the plug.
I completely get why the shop quoted something like $700 for plugs.
My hands and back hurt.
