Review on 🔋 Denso 234-4800 Oxygen Sensor: Reliable Performance for Enhanced Fuel Efficiency by Geoff Yates

I bought this O2 sensor because Denso is the same brand that Toyota uses. I've read on internet forums that other brands don't work. This is my first time installing O2 sensors and the job was easy as I found a YouTube video explaining the process. I would give 4.5 stars if I could just because Denso doesn't have vehicle specific instructions either in the box or on their website. It would be nice if Denso would let me know what size wrench is required and that the heat shield needs to be removed on my 2003 Corolla. The 7/8" wrench worked great, no wrench was needed for the O2 sensor. 22mm would also be ok.
