How do I check fitment before buying Subaru Legacy 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 Subaru Legacy 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.
