AEM Exhaust Gas Temperature Probe (EGT)This EGT probe kit consists of an exhaust temperature sensor its weld bung and an electrical connector/loom. Unlike most exhaust temperature sensors it consists of a single K-type thermocouple and the probe is made of platinum (in a protective tube made of Inconel).This gives unprecedented performance the signal of the sensor is linear from -40 ° C to 1000 ° C (200 to 849 Ohms) high accuracy and protection from outside factors (air flow humidity etc.) to achieve very rapid changes in temperature.For further technical information please see official AEM documentation.
