13 ES 350 Oxygen sensors
 

fixing my car at the collision. Apparently my O2 sensor needs replacement. I need advice on where to get the best affordable one. I am looking for "Upstream O2 sensors Bank 1 Sensor 2" I am in this dilemma because I no longer
trust my collision guy unfortunately I am in it already. I do understand how my o2 sensor could have been damage from a crash without impacting the engine, etc. Anyways, I just need someone to point me in the right direction (I already know about Lexus dealers please).

Try Autozone, Advance Parts, or O'Reily's.

You can get a Denso upstream oxygen sensor for your 2013 ES350 for $75 here:
