My 92 sc400 might need o2 sensors. I am gonna replace all 4. Anyone use universal o2 sensors? How is the quality, bc it is over 50% less. Also, is the rear 2 in the sc400 2 or 4 wire? Any experiences with universal o2 sensors will be helpful.thanks

I never use them,but I saw them on some of the customer car. You will have to cut the wire from OEM and soder those wires together because you have to reuse the OEM connector.
