anyone running these???

"Amazon: PartsSquare 4pcs Oxygen O2 Sensor 234-4169 234-4603 Upstream&Downstream For Lexus SC400 LS400 4.0L: Automotive"

are this the correct parts #

found this on an old post are these for the SC400?

DENSO numbers I found: 2344138, 2344630, 2344167 (2)

Thank you for your support!

I looked around and I am getting different part number of a set of O2

Retrieve code 21, I am sure after that I will get another code over 250 K

So want to ensure I am getting the right part number for Denso preferably but the first 3 are all 4 for under 100 dollars...

 

Moved to Performance and Maintenance and removed direct Amazon link, (sorry...).

LEXLUIS, I personally haven't had experience with that brand O2 sensor. Maybe someone else has, though? Personally I'd stick with the factory Denso P/N's and just shop around. Have you tried Carson Toyota, Pembroke Pines Lexus, Lexus South Atlanta or Amayama?

 

Thanks for relocation and apologies for bad placement.

(Is been a While since I been active on the forums 2004 in fact at SVT

After much looking around I came up with only two part numbers

upstream 2344211

downstream 2344619

Out in the WEB and based on year or model part # changes and I was confused as to upstream bank 1 # was different than upstream bank 2 #
however Downstream is the same number for both sides.

It seems to me and correct me if I am wrong that there is only two part numbers.
I will give those reference a shot and thanks for your assitance

 

bump part # please

upstream 2344211

downstream 2344619

 

LEXLUIS-- I just checked and yes, for an SC400 (pre OBD2 and VVT-i version at least but possibly for those as well), those two Denso O2 sensor part numbers are correct.
