I would like to install this new style transmission cover so I went out to the garage to eyeball that area. Boy, it sure looks like it will come really close to the wires and end of the O2 sensor. Any of you guys that have done this notice this or have any comment on the fit ?

I installed the new engine breather cover assembly (part #29400448, $87.95) from the CVO 121 engine onto my 114 FLHP transmission housing. I used this to create an external breather that is not routed to the engine air intake.
Here are the stock and new transmission covers compared (new on top).
Here's a video from H-D showing how the new breather works.

I routed a 9mm ID silicone rubber vent line from the breather fitting out the rear of the bike as you can see here.
I removed the stock rubber breather tubes that direct combustion blow-by and oil vapor into the intake. The throttle body was noticeably sooty and oily inside. I replaced the stock breather bolts with 3/8-16 x 1.5" button head cap screws and plugged the small hole for the stock breather tube in the back of the air filter with a 5/16" rubber grommet style plug from an auto parts store.
