Successfully Changed Both Pre-cat O2 Sensors!

I know this is a minor repair, but can you believe the dealership wanted over $700 to change both my pre-cat O2 sensors after the Malfunction Indicator Lamp (MIL) / Check engine Light went on?

Time spent was well worth the $500 saved.

Finished doing a write-up on it:
