Everyone always says go OEM, well I say they are wrong! The price of one OEM sensor is over $250!
03/23/2022 Update: The air fuel ratio uptream didnt work, click here to see the AFR O2 Sensor I installed in my Prius Plug-in
I’ll update this page in a day or so, but I was able to purchase both Bank 1 Sensor 1 and Bank 1 Sensor 2 O2 sensors for my 2013 Toyota Prius Plug-in for a significantly lower price by not purchasing OEM.
I ended up finding out that the Automotive-leader 89467-04060 Air Fuel Ratio Upstream AFR Oxygen O2 Sensor for Tacoma Sequoia Tundra 4Runner Land Cruiser, for Lexus IS250 GS350 IS350 GS450H LS460 GX470 LX470 LS600H 89467-04020 works perfectly in the Toyota Prius! This is for the Bank 1 Sensor 1 sensor.

Later tonight, I will install the Bosch 18039 Premium OE Fitment Oxygen Sensor for Select 2010-19 Lexus CT200h, RX350, RX450h; Toyota Highlander, Prius, Prius C, Prius Plug-In, Prius V. This is for the Bank 1 Sensor 2 sensor.
