ITEM NAME:1X(Oxygen Sensor Upstream Sensor Replaces For Bosch 13477 MHK000210 BMW 318Z1Z4) 1X(Oxygen Sensor Upstream Sensor Replaces For Bosch 13477 MHK000210 BMW 318Z1Z4) 1X(OE quality Compatible with Bosch 13477 Denso 234-4672.Features double protection layer, aluminum oxide trap layer, PTFE filter and stainless steel housing.Please check the Make Model Year Position Length before purchasing it.The metal shroud doesnot look as shiny as other Oxygen Sensors. Because it is made of SUS310 high temperature resistant material. And every single item is heated at 1562℉. The high temperature also mskes it stands wear and tear. Zirconia Sensor:An important property of the zirconia Elementss is that it can contuct oxygen ions above a temperature of about 350℃. When the sensor is fitted, the outside of the zirconia Elementss is exposed to the exhaust gas and the inside is in connected with air. Both sides of the Elementss are coated with a thin layer of platinum that act as electrodes and cary the sendors' signal(volatge) from the zirconia Elementss to the lead wire. At operating temperature, oxygen ions are able to pass through the Elements and deposit a charge on the platinum electrode thus generating the voltage signal.A New Oxygen Sensor Impacts Your Vehicle !Helping ensure your engine being constantly monitored and operating efficiently, while maximizing performance.Saving the fuel and cost by regulate air-fuel mixture by checking the oxygen content in a vehicle’s exhaust converter.
