o2 sensors.

Is it at all reasonable to put a used working condition o2 sensor in a vehicle or shoudl they always be new? My 626 has two and they're both 106 bucks for just the universal not even an oem:eek:

u can get a used one, but thats like using used oil when u do an oil change.

o2 sensors are a part of regular maintenance, (about every 100k) so just spend the money to get the proper ones. id probably get the proper replacements, but not from the dealership.

They're a fuckin ouch god damn 106 for a universal.
