Gs430'01 Oxygen Sensor Part Number

[nester]

I am going to replace 2 front Oxygen sensors on my GS430'01.

Which part number should I look for? There are a lot of different numbers even among Denso - e.g. front left: C5010-112388; W0133-1604947; 2344138 for $110-$150.

Which one would be more "OEM-like" and also which site is the most trusted and reliable to get original parts?

i was needing the same. i went with an o2 simulator instead. it is cheaper and you can get headers if you want afterwards.

it is only $30 and make sure you get the dual output simulator. now you can also get headers if you'd like without a CEL.

Thanks anyway but it's not for V8, not the front and I need real sensors, not the 'plug'..

Anyone knows about part numbers?

Not a v8? a 430 is a V8. You can call up your local lexus dealer and get the part numbers then instead of getting it from them contact oxygensensors.com or rockauto.com with the OEM part numbers and they'll get you the right parts. I've used both but without getting the OEM part numbers, both sites tell what sensors are OEM type and what banks they go to.
