eurotec :

Hi, bank 1 is always the side that contains #1 cylinder. In your case it will be the passenger side.

Customer:

What about removal and installation instructions and special tool(s)?

eurotec :

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.

Customer:

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?

eurotec :

A lot of parts stores carry the sockets or similar wrenches for removing oxygen sensors.
