Product Q&A

Can these hold up high temperatures, im running long tube headers on my 5.3 Silverado??Tony_M10May 10, 2022
Best Answer:Hello! Yes, they can

I replaced all my o2 sensors 1000 miles ago, now I have codes they are bad. I’m lost what to do?Robert T.Jun 25, 2024
Best Answer:Hi Robert, thanks for initiating contact. If you've checked the basics and the codes keep returning, it's best to have the vehicle scanned by a professional to pinpoint the underlying cause before replacing any more parts. Oxygen sensor codes can have a variety of triggers beyond just the sensors themselves. Have a nice day.

I have a 2012 LTZ Avalanche.  Without taking my 02 sensor out first, is there a way to know if it's  a 2, 3 or 4 wire sensor?  Also are the 2 in front & the 2 in rear the same?John O.Mar 10, 2024
Best Answer:Hi John, thank you for reaching out. The oxygen sensors of the 2012 Chevrolet Avalanche LTZ have four wires. You can check the number of prongs on plug of the original part. The upstream oxygen sensors are different from the downstream oxygen sensors for your vehicle. This product consists of two upstream oxygen sensors.
