The one I got was authentic. works and fit great.
234-4260 is a Direct fit for O2 sensor for 2009 Lexus ES350 sensor Bank 2 Sensor 2 aka Downstream Left. Whoever confused of which sensor it is this is it. I got it confirmed it's Denso authentic the one I have received. It looks more updated than the original denso from toyota denso that came out of the car. As of now it is going great and easy to install. Sensor looks high quality and it was on sale on amazon so the price is amazing.

Fit 2007 4Runner V6 driver’s side, closest to ground.
Worked great on my 2007 4runner with the V6. Fit on the drivers side, closest to the ground. Took all of 15 minutes to install. New threads even came with a little anti seize on them. Installed, cleared codes, codes did not return.

Amazing! Cleared codes!
Genuine denso part (makes OEM parts for Toyota) at a great price. Installed on a 2005 Tacoma V6 4x4 and it fit great. Wire was perfect length and the quality is superb. This sensor cleared my P0128 and P0606 codes. I highly recommend. Super easy to install yourself, just purchase an O2 sensor tool and PB blaster. Attached are photos of the 20 year old Denso sensors and the wire connectors (again, for a 2005 Tacoma) so that way you Tacoma drivers can ensure this is the correct part for you. Thanks!

O2 sensor
Highest rated and the most expensive but seems to be working good.

OEM Quality, easy to install.
This was a perfect replacement for a Toyota 4.0L v6 rear downstream o2 sensor. Item clip fit the factory harness securely, and had a protective plastic cap on the sensor to keep it clean during shipping. Replacement was easy to do, but hard to access laying on your back under a car. I did this on car ramps for the front. Stay safe and set the parking brake and use jack stands. This fixed/cleared my check engine light code (P040#)! Only minor thing ..and more of a suggestion is that the vendor provide a small tube of antis-seize lubricant to aid in installation.

Does not fit Lexus GX460 Bank 2 Sensor 2 replacement
Supposed to be an "Oxygen (O2) Sensor with 4 wire 9.45 inch long wiring harness" The wiring harness is too short for a Lexus GX460 Bank 2 Sensor 2 oxygen sensor. The entire module (sensor and harness) id barely 9 inches long.

This fits my 2009 Toyota Camry LE 2.4 liter
It works great! This part fits my 2009 Toyota Camry LE, ATM, with the four cylinder engine 2azfe. It's installed on the lower front exhaust pipe that curves down under the car from the catalytic converter near the flex joint. It's different from the one that goes on the catalytic converter that's bolted to the exhaust manifold on the engine. The wire length is a perfect fit at it's listed length of 9.44 inches. Don't buy the other sensor that has a wire length listed at 12 inches, wrong part. Correct part #: Denso 234-4260 Down stream heated oxygen sensor.

I had a mechanic install it after determining this was the part needed through a scanner purchased from Amazon. Issue resolved following install. Price much better than from dealer or mechanic.
