I have an 2003 Rodeo S (V6). Any recomendation on which 02 sensors, and part numbers, to get? Any tricks or things to watch out for when replacing. I was going to do all four (I think there are four) and get it over with. Thanks in advance for any help.

Why are you replacing? Getting codes?
I'm still on the originals (all 4) on a 2001 Passport with 130K miles. No codes; no problems.
Just order them based on the vehicle series/motor. Be sure & get 4-wire/heated. An O2 sensor is pretty generic, there's a wide range of units that will work. They'll cost you between about $35-$65 depending on whether you get Denso OEM's or other aftermarket. Careful, some (cheaper ones) don't come with the connector. You have to splice them in from the originals. Not a big deal, a little solder & wire shrink-wrap does it.
Nothing complicated about replacement. Just be sure & use plenty of anti-sieze on threads when you install. Else, you'll never get em out again. They usually come from manufacturer with a dab of anti-sieze, but it's not enough IMHO. I add more.
