Bank 2, Sensor 1 Right-bank Pre-catalytic Oxygen (O2) Sensor

No interferce problems here. I was able to remove the right-bank, pre-catalytic oxygen sensor directly with my 22mm oxygen socket (see inset).

As I did with the left-bank, pre-catalytic oxygen sensor, I spread some anti-seize compound included with the new oxygen sensor in the Denso box (pictured earlier) before tightening down.
