How in the F*@$ is everyone changing their front O2's... i am in the process of cleaning the TB, MAF, and new IAC, PCV valve, COP's, and i have my new o2's here and i cant get to the front ones... the clip for them is almost beyond reach and there is no room for a wrench to get them out i'm about ready to take it to the dealer and have them aggravate themselves with it... its a 2002 Fx4.

ok, now the next question i have is i have the oxygen sensors Part # 15717... will those work, or should i swap them out for the 15716's since i have to go to the parts store anyway...???

 

The different #'s are wire lengths - short and long. If your stock , shorts are what you want. Headers (LT's) you'll want the long wire. Shorts are only about 6"'s.
