Bosch Wideband 5-wire O2 sensor-17025

Bosch LSU 4.9 5 wire heated O² sensor. Bosch part # 17025 Length: 1000mm (39.37") This is the latest Bosch o² sensor that we use exclusively with our Wideband AFR kit. The newest generation of oxygen sensors are being called "wideband" lambda sensors or "air/fuel ratio sensors" because that's exactly what they do. They provide a precise indication of the exact air/fuel ratio, and over the broadest range of mixtures - all the way from 10:1 to 20:1 air/fuel ratio. The Bosch LSU 4 wideband oxygen sensor is a 5-wire sensor that reads oxygen in much the same way as a traditional oxygen sensor. but it uses the latest "planar" construction with a special two-part sensing element to measure how much oxygen is in the exhaust. The Bosch LSU 4 wideband oxygen sensor has a response time of less than 100 milliseconds to changes in the air/fuel mixture, and reaches operating temperature of 700 to 800 degree Centigrade (1,400 degree F) within 20 seconds or less using its internal heater.
