Review on 🔧 Improved Denso 234-5430 Air-Fuel Ratio Oxygen Sensor by Jonathan Self

There was a CEL which indicated my O2 sensor failed most likely after 140,000 miles. I was lucky that the replacement took about 30 minutes with the right tools, borrowed from an auto parts store, and the part wasn't "hot welded". thread, but do not specify what is the small, unmarked, copper-colored "grease" bag that came in the box (this is the anti-seize to use for this application, as that type is the sensor not contaminated) or that there is something else in the box besides the O2 sensor. I think if you're looking to replace a sensor, you should know what a pocket is. However, this is any fairly easy and straightforward repair for some cars that specifically mentions the use of anti-seize agents but doesn't mention that they're even in the box or in the instructions. This should be improved and included.
