9919 Wide Band Lambda 02 Sensor

For professional tuners and riders using auto-tune modules, the Feuling Wide Band Lambda O2 sensor is an essential tool for achieving a perfect air-fuel ratio. Unlike standard narrow-band sensors that only toggle between rich and lean, this 5-wire wideband sensor precisely measures oxygen levels across a much broader range. This allows the ECU or tuning module to make much more accurate adjustments for peak performance. The sensor features an 18mm thread, a 23-inch wiring harness, and true direct-fit OE connectors for a seamless installation. The threads come pre-coated with anti-seize compound right out of the box. This universal sensor is built with a robust design to ensure longevity even under the high heat of dyno tuning and aggressive street riding. It is sold individually.
