    Stock bosch. But why do you need to change them out? You know there like 80 bucks a piece.

    Narrow-band...........AC Delco. period.

    Narrow-band Bosch's lie to your computer.

    However, wide-band Bosch's are ok.

    Best prices for AC Delco...........rockauto.com

    Re: Best o2 sensor Brand?

    ok i found them on Rockauto for $50 each...they are ACDelco AFS-105 but i cant find out how long they are.....i hear the stock ones are a hair more than a foot...so i need them to be about 13" but 14" would be better to be on the safe side

    Just get some O2 sensor extensions, $25 bucks a piece from Casper Electronics or Summit racing. I dont see why different brands would necessarily be of different lengths.

    well, the boschs that my brother got are 18" long and the ACDelcos that im probably going to get are 14.5" long. i just figure since im at about 108,000 miles that its a good time to change em....itll start over fresh with the new longtubes....plus i dont have to baby the old ones while doing the header install

    Cool I'll have to remember that. When i did my headers I had to lengthen the trucks O2 sensor harness on 1 of the sides. If I ever do it again, i will be buying O2 wire extensions. I have had soem issues with the salt water penetrating my crimp/solder job causing a rcih condition on teh 1 bank. Proper O2 extensions will just rule that issue out for me in teh future.

    AC Delco all the way. I have seen many a GM vehicle have problems with aftermarket/non-oem O2 sensor communicating with the PCM.
