What makes LSU 4.9 superior to LSU 4.2 is not only because LSU 4.9 uses an electrical reference signal, and LSU 4.2 uses the reference air, but also because Bosch significantly improved every aspect of the LSU sensor in the 4.9 version, and made it a mass production level, with superior reliability and quality.

Bosch LSU 4.2 Lambda sensor, and all required looms and accessories: the fuel control table at the specified load and #15006 kit with short loom - length 2.6 m

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, determining the lambda value. Compatible with unleaded gasoline, ethanol gasoline blends, methanol, and diesel.

The wide band lambda sensor LSU 4.2 is a planar ZrO2 dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of lambda 0.65 to air makes the LSU capable of being used as a universal sensor for lambda 1 …

The wide-band lambda sensor LSU 4.2 is a planar ZrO2 dual cell limiting current sensor with integrated heater. It is used to measure the oxygen content and the lambda value of engine exhaust gases.

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, determining the lambda value. Compatible with unleaded gasoline, ethanol gasoline blends, methanol, and diesel.

The wide band lambda sensor LSU 4.2 is a planar ZrO2 dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of λ = 0.65 to air makes the LSU capable of being used as an universal sensor for λ = 1 …
