Universal o2 sensor wiring?

Does anyone know the correct colors to match? The OEM has 2 white, 1 grey, and 1 black.

The Universal has 2 black, 1 white, and 1 blue.

Did the universal sensor work for you okay? I really wouldn't mind saving 100bux and not getting an oem one.

There have been issues with the universal bosch O2 sensors in the pre cat position. It has something to do with the readings not being as accurate. See link for all the details https://www.northamericanmotoring.co...placement.html

The recommended non OEM for the pre cat is the NGK 25648. I purchased mine from Summit Racing http://www.summitracing.com/parts/NGK-25648

Which codes are you getting?

There is one sensor pre cat and one sensor post cat. Depending on the codes it might be more then just the sensor.
