FAQ:

  • Can I replace the oxygen (O2) sensor by myself?
  • Yes. However, it is better to let a professional technician help you replace the oxygen sensor to better maintain your car's discharge system.
  • What might be the problem when my check engine light comes on?
  • This may be due to damage to the sensor probe, damage to the sensor body, internal failure of the sensor, external electrical failure or other problems.
  • Why is the fault indicator on?
  • If the fault indicator is on, it does not mean that the sensor is faulty. Different trouble codes mean different situations. Please judge the code carefully and find out the real problem.
  • Can the BLPextrm OE O2 sensor help my vehicle maintain discharge performance?
  • Yes. The BLPextrm OE oxygen (O2) sensor can help the on-board computer on the vehicle adjust the discharge ratio to maintain good discharge performance.

They fit my 2007 Suburban 5.3L with no issues. The upstream sensor has a different style tip from the one I removed but it works fine. A good value assuming that they last a long time.

I m giving it a 3 for one reason.. so it was the right one and fitted well. My problem was one of the o2 sensor was stripped right out of the box and only was able to use 3 of the four sensors. It was nice orice for the money but be carefull when doing products testing and before you ship as you shouldnt strip the threads

I matched the O2 sensors to my car but only the number 1 on both sides fit. The #2 weren't even close.
