Feuling Parts Sensor Lambda sensorRef : FELG00018A / 18611647

O₂ SENSOR FEULING PARTS (Ref. 9908) — Front lambda sensor designed to ensure proper fuel regulation and emission control on road and touring machines. A replacement component for exhaust systems, this sensor provides an accurate reading of the oxygen content in exhaust gases to properly fuel the injection and engine mapping.

• Type: O² (front lambda sensor)
• Thread diameter: 12 mm
• Connector: grey, 4 wires, length 52"
• Material: stabilized zirconium dioxide ceramic body
• Finish: platinum electrodes, porous ceramic to limit erosion
• Unit: each
• Manufacturing: United States — quality equal to or better than original

A lambda sensor in good condition prevents increased fuel consumption and excessive emissions: a slow sensor can lead to up to 10–15% overconsumption. The average lifespan is generally between 30,000 and 50,000 miles on a properly tuned engine. An ideal part for heavy touring bikes and high-displacement customs — notably including Harley-Davidson CVO/Road Glide/Street Glide models — it integrates into exhaust systems to maintain the accuracy of engine management.

Replace the original sensor with this FEULING PARTS reference to regain reliable gas readings and maintain your motorcycle's performance on the road.
