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/
I know a guy in Campbell that can do this in his garage for waaaaay less, his screen name is MontegoChris, he did both of mine for a price so low I can't post it here
