Which part numbers appear in more than one listing for Lexus GS oxygen sensors?

How do I check fitment before buying Lexus GS oxygen sensors?
Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position. Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.
Check compatibility before buying
These listings were found using Lexus GS oxygen sensors search terms. A search match does not establish fitment. Compare the part number, vehicle year, generation and engine with the seller's compatibility details. Confirm delivery, returns and the final price on eBay before ordering.
