O2 Size

Howdy out there.
What size are the O2 sensors on a 2011 Ultra Limited?
12mm or 14mm?
Thanks,

If you are referring to wrench size, I just took mine out last night. 14mm. Bike has 3500 miles on it. They came out VERY easy. Waiting for my Jackpot pipe to arrive tomorrow.

So that would probably make them 12mm.

Thanks for your help.

The 2010 up bikes have 12mm sensors that take a 14mm wrench. All bikes with the small sensors have them mounted at the collector. The earlier bikes with sensors had 18mm and they were mount right below the head.
