O2 Sensor
I installed the O2 sensor I ordered from A1 Auto and evrerything was perfect. The plug was an exact fit and it came with anti seize already on the threads. Best of all it got rid of my engine code.

Elesban A August 17, 2018
Yeah, they are the same on both sides upstream. Just watch for the connection to the wiring harness to be right for your model. Either oval connector or rectangular.
