O2 sensor wrench

[Hot Shot]

I'm going to install my DP this weekend and it says I need an O2 sensor wrench/socket. Are these a special size or type of socket? I found some online that are 22mm or 7/8. Is that a standard size for all O2 sensors?

Thanks,
James

a nice cresent wrench will do the same thing

Is there room to maneuver a crescent wrench in there when pulling the DP? I have not gotten underneath to look yet.

couple years ago, i bought a 3 socket set w/a hard case cheap on ebay. i used 2 of them so far. i think it's standard size cause the 3 i got are all 7/8-22mm just diff shapes for diff appls. or as 808 mp5 says cresent wrench um.
