O2 Socket Necessary?

[msmmiami]

Hi all, replacing all 4 O2 sensors on my 2001 C4. Seeing conflicting info on the recommendation for an O2 sensor socket vs a 22mm fixed/adjustable wrench. Can all be accessed with a wrench? Would job be easier with a socket? Thanks.

Well now that I completed the project, I'll answer my own question

Yes, an O2 socket is necessary; an offset version. And nice to have a breaker bar handy as well as a wobble socket.

Dear msmmiami,

Thank you so much for helping msmmiami figure out his problem ,ha. Seriously, I bet you helped quite a few folks figure out a concern ahead of their similar project.

What O2 socket did you use? I could not get 2 of the 4 removed from
My 08 997.1 turbo even as the muffer is out of the car now.
