Denso Part numbers for O2 sensors

Had trouble finding these, Denso part numbers for OEM o2 sensors

 

This is for an 04 4.7-- assume its the same for 00-04, maybe 05-06 as well.

 

I just got a downstream denso sensor from rockauto, their catalog system is pretty intuitive. Cheaper than anywhere else too...

You hafta be really careful posting part numbers like this.

Sensors vary on these trucks whether it’s 4WD or 2WD due to clearance differences, and of course V8 or V6, and I’ve even seen differences otherwise, but … yeah. Never trust what anyone says here always, always look up your O2 sensor part numbers at www.densoautoparts.com , never get the “universal” sensor (always the “exact fit), and know that some years list the upstream as an “air/fuel sensor” instead of “oxygen sensor”.

Never assume your part number will work for others - pretty spendy part - Good way to potentially screw someone over.
