Review on 🚗 Denso 234-4517 Oxygen Sensor: Achieving Optimal Fuel Efficiency and Emission Reduction by Noe Spooner

Perfect OEM replacement for my IS300. My check engine light came on and I checked the code. It was an oxygen sensor. Replaced it with this one and all is good. It was pretty easy to replace since I ordered a sensor socket (things go a lot easier if you have the right tools). I highly recommend buying a sensor plug if you are replacing an oxygen sensor. Apply a little PB Blaster to the sensor the day before attempting to remove it and it comes off very easily. The hardest part for me was getting under the passenger seat to unhook the wiring harness. Everything else went smoothly. Great product for direct OEM replacement in Lexus vehicles.
