NGK / NTK OZA851-EE21 / 94594 Lambda / Oxygen Sensor Zirconia O2 Exhaust Probe Lambda sensors are oxygen detecting devices that are fitted into the exhaust system of increasingly more internal combustion engines. They are a vital part of the emission reduction technology & also help to ensure that the engine is running at its optimum performance. NGK Spark Plug Co Ltd was a pioneer in this field & is now a world leader in the development & production of Lambda sensors under the NTK brand name. The zirconium dioxide lambda sensor is distinguished by the following characteristics: Fast operational readiness Temperature resistance Not sensitive to hydraulic shock Resistant to contamination High level of reliability These sensors are used as a regulating & as a diagnostic sensor, depending on the vehicle.ITEM
