Question: Is this for upstream ?Ever P. / Jun 04, 2025
Hi Ever, thank you for reaching out. This is mostly a downstream oxygen sensor but may fit upstream positions on certain models. It is not exclusively an upstream sensor. For example, on some 2013 GM trucks like the Silverado 1500 and Sierra 1500, this sensor is listed for both upstream left and right positions, but predominantly it is known as a downstream sensor for earlier models. I suggest calling our parts specialists at 1-866-529-0412 (live agent assistance) during office hours to provide the complete vehicle information so we can help you find the right part. Have a nice day!

Question: Are they compatible with vin O ?Leo / Apr 08, 2025
Hi Leo, I am pleased to assist you. The compatibility of this sensor with your specific vehicle depends on multiple factors, including the vehicle's make, model, year, and engine specifications. The character "O" in a VIN typically represents the engine code, which identifies the engine type installed in the vehicle. I suggest calling our parts specialists at 1-866-529-0412 (live agent assistance) during office hours to provide the complete vehicle information so we can help check compatibility. Have a nice day!
