2014 up Z with CEL on MD ART pipes

I swapped my original secondary O2 sensors at 75k-80k miles. The one on the drivers side was just not reading right. It had been this way for a year or more. Very slow to read low to high on my torque OBD2 app. The passenger side O2 sensor read fine, but I change these sensors in pairs. I got them on Amazon, the same ones as Nissan would happily gouge you for them. Last time I checked Nissan wanted double this amount.

The original primary O2 sensors are still on the car. I do not use any of the quick fix anti fouler or other interesting attachments. They are mounted right into the Berk HFCs directly sensing the exhaust flow.
