The car listed above is an LT model.

Hello, looking to change out my O2 sensors and need to know locations and banks for all 4. Also, do you suggest sticking with OEM parts for the O2 sensors?

Sure, here are the locations for all 4-oxygen sensors and I have included instructions for changing them out as well. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:

This is extremely difficult to understand. All of the numbers and description of sensors are labeled differently in each picture. Please look at the pictures I uploaded to see if I understand correctly. Thank you
