Review on ๐Ÿ”ฅ ACDelco AFS106 Heated Oxygen Sensor - GM OE for Enhanced Engine Performance by John Mejia

Revainrating 5 out of 5

Factory replacement is the way to go.

I needed to replace the catalytic converter on my '99 Tahoe and thought I could change the O2 sensors at the same time. I went to the aftermarket with a converter (Magnaflow 23453) but have heard of a lot of bad results with non-standard oxygen sensors. So I took two of these, two from the AFS105, got the job done and years later still no problems. There are cheaper options, but save yourself the headache and buy an ACDelco just to replace the sensors.
