Could someone please link me to the best bang for your buck sensor on RockAuto that fits Bank 1 Sensor 1?

They are all listed upstream/downstream....not sure what that is.

 

Upstream sensors are the ones before the catalytic converter.
Downstream sensors are the ones after the catalytic converter.

 

And 1 comes before 2... So OP you need...?

 

Wow you guys are kunts. Can't just say the exact ones so I don't have to guess when I'm making a fkin order?

 

what year is your car.

Lol, you're such a baby. You don't come on here and expect to be handed what you need. Now you'll be lucky if anyone helps you out anymore. The fact you didn't even know which O2 sensor to get (a simple Google search would tell in less than a minute) makes laugh that you'll actually know how to replace it, that's if you buy the right one lol.

 

We are here to HELP you work on your car, not do it FOR you. If we do it for you, you will never learn. If you want someone to do it for you, then take the car to a mechanic. He will be happy to do it for you.

But until you get that chip off your shoulder, don't expect anyone to help you.
