Fueltech Bosch LSU 4.2 Wideband O2 Sensor

The Bosch LSU 4.2 Wideband O2 Sensor supports closed loop O2 maintaining optimal fuel delivery by delivering accurate measurements of the engine's air-fuel ratio to the ECU in real-time.

• Compatible with unleaded gasoline, ethanol gasoline blends, methanol, and diesel.
• Thread size of M18 x 1.5
• To operate the sensor effectively, it must be paired with a wideband O2 signal conditioner (also referred to as a wideband O2 controller). When paired with a FuelTech wideband O2 sensor controller, the sensor is automatically calibrated. 
• Remember to handle wideband O2 sensors with care and never remove the O2 sensor connector during operation. If you have any specific applications or questions, contact our Tech Support or Sales department.
