Oxygen Sensor – Ford (HL3Z-9G444-B)

Ford Motorcraft builds this Oxygen Sensor to the same footprint as the original; the catalogue number is HL3Z-9G444-B. It reports exhaust oxygen content so the ECM can hold its fuel trim. Confirm the number on the part you are removing matches HL3Z-9G444-B before ordering; superseded numbers are the same component under a later release. Shipped from our US warehouse with tracking.
