Do not get O2 sensors from Advance or any other big box store. Use genuine AC Delco. They do cost a premium but they are worth it for reliability.

You also won't need 24" long extensions. I think I used a 12" on the passenger side and didn't need an extension on the driver side.

Maybe my post wasn't clear, but do not buy anything other than AC Delco (that includes Bosch...ESPECIALLY Bosch...)

Yeah go with what Ramair is saying. Definitely the ACDelcos... They do cost a bit, but compared to having to replace them Boschs it's worth it.

Only need 1 12" extension for the pass. side. I got a 24" thinking "just in case" and it was way too long.

I bought 2 12" O2 extensions from them and they were both plenty. Well made, but I don't remember them being $20 when I did.

RockAuto is a great place for o2 sensors, the best prices ive seen, better than Summit and about half off from local part stores. I use Bosch and AC Delco on my Pacesetter longtubes they both work fine for me.

Why F Delco? And how exactly do you know they are the same? Not just "they look the same".
