Hi, bank 1 is always the side that contains #1 cylinder. In your case it will be the passenger side.
What about removal and installation instructions and special tool(s)?
There is not much to it. Just locate the sensors in the exhaust, disconnect the harness and unscrew the sensor. Click here for some instructions.
It looks like I need to get a ring wrench socket. Is that something that is available a a regular car parts store,or I need to order it somewhere?
A lot of parts stores carry the sockets or similar wrenches for removing oxygen sensors.
