Need help identifying correct O2 sensor
Chevy Silverado 1500 (2001) 4wD I have a bad O2 sensor on bank 1 (pre cat).....There is a bosch brand and I believe there is a Denso brand. I have no idea which one is on my truck. Can anyone clarify?

It doesn't matter which brand. Bosch is usually better in quality.
