Hi all. I'm in the process of tuning with ZFG and have been told that my upstream O2 sensors on both sides are failing mid-pull while data logging. The recommendation is to replace both sensors, but I'm having a hard time finding anything available online. The normal Napa, Advance Auto, Auto Zone, etc. stores have nothing available, and a few online parts sites have some but 3-4 week ship times.
Anybody have a recommendation for upstream O2 sensors for my 2020 ST? I'm trying to avoid paying dealership prices for a sensor.
