I need to install o2 sensors back in my pipes. I'm running a thunderheader now with plugs in them. My question is do I need the speacial socket from HD to install them with the pipes on the bike or is there enough room for a wrench between pipes and jugs. Thanks

 

Not familiar with your pipes but I wouldn't think you would. Try it first without the wrench.

 

Is this the right part #27719-07

 

I'm not sure of any clearance differences between the 08 and 09, but when I yanked my o2's (on my 09) I used a standard o2 sensor socket. (Deep socket, with a cutaway). And a socket from a parts store has gotta be cheaper than the HD equivalent.

 

Yep...What Frogger said!

 

Just took mine out to replace the pipes, used an old 7/8's combination wrench that I bent a little, didn't buy a special tool. Just unplug them and use the wrench, it works. When you replace them don't forget to put some anti freeze on the threads and be careful.

 

Copper anti freeze. Bosch 12028. $19.99 as opposed to $40+

 

Are these Bosch one's a direct replacement? Connectors the same?
