Yes both are the exact same sensor. They just have different codes to specify which bank and sensor it is. Buy two.

Great price!

Yes, since you're experiencing a raw fuel smell AND a lack of performance it's definitely more than just aftermarket bolt-ons causing the issue. Hopefully your new sensors will set you straight! Make sure to apply anti-seize onto the threads of the new sensors; avoid getting any on the sensor-part of the item though.

Should come about a week. Dealer want $260 each and Oreilly want $180 each. I have watch some YouTube vdo on how to install them. thank you for your help.

What is anti-seize? Driving for 2 day after reset battery, new MAF Sensor and Seaform injector cleaner in gas tank. And no check engine light yet. Car still run slow and lack of power. Hopefully when I install 2 new A/F Sensor in about a week or 2 it will help.

I have not seen a video of our specific year and model nor a DIY. If you find am exact video then it'll help, if it's for a different model it will be different

Same as IS350. The YouTube title is under.

"Lexus IS 250 Oxygen sensor replacement".

Not such a great DIY but its the basic. DONT use the sensor socket.That is used for sensors that arent seized or rusted oem from from factory. You wont be able to crack it. Instead just use cutter wires and snip off the wiring. This way you can use a 1/2" socket and break it with no problem. I was at that bad boy for a while and it still wouldnt crack, even with spray. Same with the drivers side, cut that wire too. You dont need that jacked up sensor so it would make sense to just cut it and slip an extension socket over it and you're good to go! Make sure you don't damage the sensor while installing it. Add lube to the threads thats provided in the box.

Thank you for the information and tip. My sensor should be here about a week. Will update about installation.

It is what you want to put on the threads of anything (bolts/sensors/etc) that you want to be able to later remove from the vehicle with ease. The anti-seize keeps the threads from binding together from the MANY heat cycles one can go through.

Basically Google "anti-seize"; you can pick some up cheap at any auto parts store.

Ok thank you.
