Hi there

Just installed a new two brothers m-2 cf slip on system on my 06 f4i. I found the 02 sensor hard to get in and the wire is extremely tight now that it is in. Just wondering if anyone else had this issue? also will it hurt the sensor with the wire being tight like that?
Thanks
Ryan

 

Mine was the same way and I never had any problems with it. If you kinda follow the wire up you can pull alittle more slack but u wont have any problems

 

whats the o2 sensor for?

 

OK Thanks Muscles! The 02 sensor takes a reading of the exhaust and sends a signal to the ecu to determine to richen or lean the fuel mixture.

 

Ill look at my 06 tom. I cant remember how tight the harness is for my O2...

 

If you can't trace the wires in order to find a little more slack from somewhere else, you can always extend the wires.

 

I got the M2 as well...just follow the wire like Aken said and work it down for more slack
