Work great on my Lexus, sensor is well built thanks for the frsat quality Denso.
BA232 –
Correct OEM part with shield. Make sure your O2 sensor tool is 2″ deep as the shorter 1 1/4 inch is too short for the shield.

I have 2010 Lexus IS 250 AWD and It was showing P0037 code for oxygen sensor
Same Denso 234-4521 Oxygen Sensor was available at local store for around $95.00
Order it through Amazon on Sunday; arrive on today, Wednesday afternoon.
Just installed it and now the code is gone
Amazon Customer –
Best price around. Installed in my 2007 Is350. Downstream so second sensor down. “Sensor 2”. You’ll need a special o2 removal tool.
Tina –
This part fit the vehicle perfectly! My mechanic it was what he expected and I am saving good gas mileage since I replaced the sensors!
Timothy –
I use this sensor in a 2009 Lexus IS250, it has a P0037 code, bank 1 sensor 2 problem. Replaced this sensor, reset the code and fixed the problem.
Amazon Customer –
Did what it was designed for.
Dan –
Good quality. Pain to install on a Lexus IS250 but worked great.
J. Umbach –
Worked perfectly as an OEM replacement for the post-cat O2 sensors on my Lexus IS350. Where easy to install and saved me hundreds of dollars for not having to go to a mechanic.
