I needed a set of new sensors for the 2002 LS1 PCM since the price for fuel is through the roof and my mileage seems to be taking a crap. Check out this guy's listing on ebay. I bought two sensors shipped to the door for $75. These are $69.99 each from autozone and Orielly just for a Bosch brand unit. ACDELCO O2 SENSORS
Be sure which connectors you have. This is for the stock LS1 connector. The male pin end is on the sensor end of the connection.
