Dealer also switched out my battery and bill is now $700, so they will be adding $1200+ to the bill with those o2s.
Also, would these be the right sensors? at http://www.ecstuning.com/Search/O2_Sensor/ES2580506/
While you have the DP's out to swap the sensors, you might as well purchase a set of catless downpipes and install them both in one go. You can then run a higher map (assuming you are tuned) and also enjoy the new found intoxicating noises coming out of your exhaust.
