Gotta love going against the grain , im using the Bosch 02 pn 12014 and its been working fine . was using the gm non heated then went to the heated one AFS74 , neither lasted that long , the Bosch one seems to be working good . And thats after a day of racing on C16 gas and some street use . The O2s on my scanmaster are fine ( when the sensor goes bad they get all kinds of weird low #s)
