I did a search, what size socket is require to remove an O2 sensor on a 2013 Heritage stock exhaust. I read 22 mm on a search, I have one of those for my civic and its huge.

which dang near the size of 7/8ths.

Doesn't it take a special Modified socket? Where does the Wire n Plug go?

Seen a few Modified Ones on this forum... See the One Coyote showed... it had a slot to get the wire out of the way so it didn't get Damaged 

IF you can get a Box end or open end wrench on it, and get some torque... I think I put a bend in one of my end wrenches to get one of mine off... I had it running to get it hot then COOL enough to Not SINGE hands to Loosen...

But Mine is an 09.... In different location plus Two Wires compared to the 2010 n up,  yours are 3 wire (heated Units)...

I'll look at mine but they might be a different size than the 3 wire Later ones.

I'll edit the size of mine "IN" ....   I'll go check...

Checked: Mine are 7/8 US Standard... looked at my modified Box End Wrench...

7/8" is 22mm trouble with the slotted sockets is they can open up if the sensor is tight. A pipe spanner ( wrench ) will work. Or you can just grind a slot in a 22 or 7/8 wrench to get into tighter spaces.

I have a 22mm wrench for O2 sensors and its way too big. I can barley get a 14 mm open end wrench on the supposedly stock ones in the exhaust now. Im heading to Harbor freight now.

The 22mm / 7/8 inch is for the bigger 18mm threaded O2 Sensors.. I don't know what the later 12mm threaded sensor size is... I guess the others didn't pick up on that either. 14 sounds good to me.. 

9/16 is the size of late sensors. 14mm can be tight.

I use a flare wrench.  7/8" for the large and 9/16" for the small. 

Some head pipes may make it more difficult to find the clearance.
