Advantages of KUHTYB O2 Sensor: ● Low power consumption(7watt) ● High temperature resistance (vent at 1000 ℃) ● Multilayer ceramic belt structure with integral heater and low quality active area. ● The very short activity time (<15 seconds) reduces the discharge during cold start. ● There is no need to adjust and repair the oxygen sensor, just replace the same type of oxygen sensor.
